Abou Diaby doubtful for weekend

Arsenal manager Arsene Wenger has revealed that Abou Diaby is an injury doubt for Sunday's derby at Tottenham Hotspur in the Premier League.

The midfielder was forced off during last weekend's 2-1 win over Aston Villa with a calf problem.

"Abou is an uncertainty," Wenger told the club's official website. "He has a calf problem, a minor one. It is question of days.

"He will have tests and then we will see if we can use him on Sunday or not. It is a 50:50. Actually, maybe a bit more for him playing."

Meanwhile, Bacary Sagna has been ruled out for the Gunners with a knee injury.
