#4 Eduardo Da Silva (2007-2010)
And yes, the next one was initially a success. Eduardo Da Silva was signed from Dinamo Zagreb in July 2007 for a fee believed to be around £7.5 million. Going into a match against Birmingham in February 2008, Eduardo had scored four goals and assisted three in seven appearances. Arsenal were five points clear at the top of the Premier League.
Three minutes into the game, Eduardo dropped deep into midfield to collect the ball, turned and took a touch. Martin Taylor of Birmingham City thought that the ball was there to win – but Eduardo was too quick for him.
What followed was one of the most gruesome injuries in the history of football. A broken fibula, and an open dislocation of the left leg. An incident that broadcasters Sky Sports deemed so graphic they refused to show any replays of it.
Eduardo was never quite the same player even after recovering from the injury. He had a decent career, with spells in Shakhtar Donetsk and Flamengo, but Arsenal fans will always wonder what could have been.
