West Ham fans react on Twitter to Jack Collison's early retirement

The midfielder has hung up his boots after a torrid time with knee problems.

Jack Collison joined West Ham United in 2005 as a 17-year-old and went on to play 113 games for the club, but it could have been much more.

Since dislocating his kneecap in March 2008 he has suffered with serious knee problems and never truly found his way back into regular first-team football.

He spent time at Ipswich Town, but never got fit and many have doubted the Welsh international's ability to get back in the game.

He returned to boyhood club Peterborough United last summer. He signed a one-year deal to join the League One club but his knee injuries have never truly healed.

Today he confirmed his retirement from the sport, aged just 27.

West Ham fans of course have fond memories of the midfielder, who also made 17 appearances for Wales, and will now look toward a future as a coach and in the football media.

He also spent time on loan at Bournemouth and Wigan Athletic during his professional career.

Since the announcement plenty of West Ham fans have been tweeting their best wishes to Collison after his retirement...
