5' 9" tall pacy right-sided player born in Freetown, Sierra Leone who later moved to England where he started his senior career in Carshalton's youth set-up.

Osman was chosen for the London Under-17 squad and during the 2004/05 season he had trials with Nottingham Forest and Watford.

In the summer of 2005 Osman featured in most of Margate's friendlies and shortly before the start of the 2005/06 campaign proper he was given a two-year contract aged only 17. Osman made his debut as a substitute in a 2-1 defeat at Staines in the Isthmian League Premier Division on 23.8.05 and over the course of the following two months he made five more sporadic sub appearances.

On 24.10.05 Osman made his first start at right wing-back in a game against Fisher at Dulwich. He was a very late replacement for 'flu victim Greg Oates who pulled out shortly before kick-off and although Margate lost 2-1 the Isle of Thanet Gazette said Osman "showed what a player he is going to be". He then started the next 12 matches in the number two shirt after Oates broke his arm and in its report on a 1-1 draw with Bromley at Hartsdown Park on 22.11.05 the Gazette said Osman's tackling was "improving all the time". The paper also said "he delivers a fine cross".

The last of Osman's run of games at right wing-back was a 1-1 home draw with Folkestone on 26.12.05 and the Isle of Thanet Gazette said he "bombed forward all day". The paper also added "the wing-back role is doing him the world of good, because he's doing a top job of learning how to get stuck in and defend. If he can do that, as well as run at defenders and pick passes as he did on Boxing Day, then what a player Margate have on their hands". With Greg Oates available again Osman then dropped to the bench for the next two matches and when he returned to the side in a 5-2 defeat against Staines at Hartsdown Park on 14.1.06 he played as a left wing-back in what turned out to be his final appearance for almost three months.

On 21.1.06 Championship leaders Reading sent a scout to watch Osman play in Margate's game against Slough at Windsor & Eton but he had a wasted trip as Osman was an unused substitute for the match. Chris Kinnear said he'd spoken to the scout and told the Thanet Times "I told him if he wanted to take him to Reading and have a look at him he was more than welcome to do so. He's under contract to us and I think he's going to be quite a good player but you've got to give young lads a chance. He's quick enough and hard enough to make a league player."

Osman didn't feature in Margate's next five games either and as speculation about his future increased he joined Fulham on a two-week trial on 20.2.06. Margate's official website said the club had "received a number of enquiries" about Osman and he played in two matches for the Cottagers' Academy side. Chris Kinnear told The Non-League Paper "We want to see him do well and won't let money get in the way. He's quick and he's strong and to be honest we don't know yet how good he's going to be. He's still a baby." At around the same time the Guardian reported "Margate's teenage defender Osman Sesay intends to spurn Reading's advances and sign a £100,000 deal with Fulham instead".

Immediately after returning from Fulham Osman joined Spurs on trial for a week and Chris Kinnear told the Isle of Thanet Gazette "If he gets the chance to go to Tottenham I'd imagine he'd jump at it and I wouldn't blame him."

Osman's next trial saw him play in midfield for Crystal Palace's reserves in a 2-1 win over Norwich Reserves on 22.3.06 and he was substituted after 77 minutes having been booked earlier. A few days later Chris Kinnear told the Isle of Thanet Gazette "He's got an agent who's touting him around but he can't keep going from club to club. It isn't doing anyone any good. I hope it will settle down in the next couple of weeks and he can concentrate on playing football."

When nothing came of Osman's trials and the national media's transfer speculation he resumed his Margate career with a substitute appearance in a 1-0 win at Hampton & Richmond on 8.4.06. He featured once more as a sub before wearing the number nine shirt as Margate travelled to Leyton on 22.4.06. Five minutes into the second half Osman was sent off after picking up a second yellow card for a clumsy challenge but Margate still won 2-0. He also played up front in the last game of the season - a 4-2 home win over Hendon on 29.4.06 - and that was Osman's last senior outing for Margate. He'd made 26 appearances (ten as sub) without scoring during 2005/06.

In May 2006 Osman turned 18 and during July and early August 2006 he played in four of Margate's pre-season friendlies before joining Blackpool on trial.

Osman featured in two reserve team games for the Seasiders during August 2006 before returning to Hartsdown Park at the end of the month.

On the eve of the 2006/07 season Margate's player-manager Robin Trott spoke to the Isle of Thanet Gazette about Osman and said "He can play right or left side but he's not an out-and-out forward, so maybe behind the front two is his position. Very quick but very raw. Hopefully with the right training he can become an asset to the club, as a player or a sell-on."

Osman didn't feature in the Margate squad for the first four games of the new campaign but on 2.9.06 he was an unused substitute for a home match against Chelmsford before drifting away from the club for a while. At the start of November 2006 he reappeared in the reserves but Osman didn't feature in the first team squad again and towards the end of December 2006 he joined Walton & Hersham on what was intended to be a season-long loan.

In the event Osman made four Isthmian League Premier Division appearances for the Swans before the Surrey club terminated his loan towards the end of January 2007 as they wanted to free up wages for new signings.

Shortly afterwards Osman signed for Dulwich and although it wasn't officially confirmed there was a general belief that Margate had released him from his contract which still had a few months to run.

In February 2007 Dulwich loaned Osman to Kent League club Croydon and he stayed there for the remainder of the 2006/07 season.

In the summer of 2007 Osman signed for Conference club Aldershot and he played for their reserves in the first two Football Combination matches of the new campaign before leaving the club in September 2007.

In November 2007 he made a single Isthmian League Premier Division appearance for Wealdstone and in January 2008 Osman rejoined Dulwich.

He featured in four Division 1 South games for Hamlet before the end of the 2007/08 season.

In December 2008 Osman linked up with Division 1 North outfit Ware and his team-mates there included former Margate players Hasim Deen and Tamba Ngongou but Osman only played once before leaving the club.

During the 2009/10 campaign he made two league appearances for Division 1 North side Leyton before relocating to the North of England sometime in 2010.

Osman had a spell with Abbey Hey in the North West Counties Football League Division 1 during 2010/11 and then returned to London.

At the start of October 2011 Osman had a brief spell back at Walton & Hersham where he made one sub appearance in a 2-0 defeat at Chipstead in the Isthmian League Division 1 South on 4.10.11 before leaving the club. He was still only 23 at the time.
