The Hammers fan favourite is leaving the London Stadium to take up a coaching opportunity overseas.

Jack Collison has taken to Twitter with a message bidding farewell to West Ham United as he prepares to leave the club to take up a coaching opportunity overseas (official website).

The 30-year-old progressed through the youth ranks and made 121 first team appearances as a midfielder between 2008 and 2014 before having a stint at Peterborough United, but his playing career was sadly cut short due to injury (The Independent).

Collison returned to the East London club two years ago to coach the Under-16s but, earlier this week, the West Ham website announced that he would be departing his role, describing it as “a unique opportunity overseas”.

Here is what the Hammers fan favourite wrote on the social media platform:

A number of West Ham fans wished him all the best and also expressed sadness at seeing him go:

According to BBC Sport, Collison has accepted a coaching role in the United States at Atlanta, the current MLS champions, who are managed by former Crystal Palace and Inter Milan boss Frank de Boer.

West Ham have replaced Collison with another fan favourite in Kevin Keen, who came through the Hammers’ youth ranks in the 1980s, made close to 300 first-team appearances, and then enjoyed a nine-year spell between 2002 and 2011 as a youth, reserve and first team coach at the club (official website).
