ARSENAL'S DIABY OUT FOR NINE MONTHS
Arsenal are 14/1 with bet365 to beat West Brom 3-0 on Saturday
Diaby has been troubled with injuries for most of his Arsenal career since his move from Auxerre in 2006 but Bould believes he still has a big future at the club.
“I've spoken to him very briefly,” the assistant manager told Arsenal Player. “I saw him just before he went for his scan. It's dreadful news for Abou.
“As we all know, he's had seven years of injuries and it takes a huge character to come back. Maybe it's a chance for him to correct everything that was going wrong. That's the positive that he can go forward with.
“He might use the seven or eight months to get rid of all those injuries that he was struggling with. We're all hoping and praying that he comes back a better player.”
