Chelsea signed Sinclair to their academy aged 16 for an initial £200,000 and he was pure gold for the under-18 team with 15 goals in 22 games.
His Chelsea career was started by Jose Mourinho in the League Cup against Wycombe. He then went on loan to Plymouth, where he scored this wonder goal.
Sinclair returned at the end of the season and came off the bench against Arsenal before making his full Premiership debut at Manchester United, where he suffered a broken foot.
He scored his first senior goal against Hull in the Carling Cup and had a major impact against Leicester, setting up a goal and causing trouble for the Foxes.
It was after this he was sent on loan and never really get back. He made four brief appearances for Scolari in 2008 before heading off to Wigan and Birmingham on loan.
He left in the summer of 2010 to link up with former Chelsea under-18 boss Brendan Rodgers at Swansea.
Sinclair was a key component in their push for promotion, scoring 19 goals, including a hat-trick in the playoff final.
He has also been a standout in the Premier League with seven goals, including one against Chelsea that handed Swansea a draw.
Right now, a lot of Chelsea fans are wishing they had a natural winger with pace who would take on an opponent—Sinclair would fit the bill.
He would likely start ahead of Kalou and Malouda and be a valuable option. Unfortunately, the only time a manager really seemed to make Sinclair feel wanted was Mourinho, and once he went, Sinclair never really got another opportunity.
