Redknapp wrote in the Daily Mail: "I’m surprised by how quickly Arsenal have gelled. With Santiago Cazorla loading the bullets, they look like they will make a lot of chances and the Spaniard is the player I’m most looking forward to watching in this season’s competition. He can thrive on such a big stage.
"They have improved at the back, too, only conceding one goal so far this season — you can see Steve Bould is making a difference. I never thought Per Mertesacker would be in a team keeping clean sheets in three out of four games."
