Diaby, who had ACL surgery last March, had to undergo an additional operation and is now expected to be out until next March, the Mirror reports. Manager Arsene Wenger said Diaby "had a little key hole surgery again, on the knee because his knee blew up every time he did something so it is not six months after the cruciate. He could not even jog yet so with new surgery it is a set back for him so competitive football cannot be played before March."

This is a major blow for Diaby, who had been dogged by injuries throughout his career. Arsenal have been perfectly fine without him, so it shouldn't be a major change to their plans, or the plans of fantasy owners.
