Arsenal boss Arsene Wenger admits the current squad is the best he's had. Wenger is delighted with the strength in depth at his disposal.
Wenger said: " It is true that the squad has maybe more strength than I have had before. At centre-back, yes, but also in midfield.
"We've Jack Wilshere and Tomas Rosicky, who are not playing at the moment, as well as Emmanuel Frimpong, Francis Coquelin and Aaron Ramsey, who are also out."
He continued: "Cazorla has provided the link between midfield and the final third. He has the ability to turn the game.
"Cazorla and Arteta would play for their country frequently if they did not come from Spain.
"They have so many excellent midfield players that not even Cesc Fabregas cannot always get in.
"As for Diaby, he is a fantastic player and he has also had a long time out through injury. He is a good example for Jack Wilshere."
