Arsenal boss Arsene Wenger was tightlipped yesterday over their transfer targets.
Wenger maintained it was "difficult" to talk about potential transfer targets - even if rival clubs do not show the same respect to Arsenal.
On Valencia midfielder Juan Mata, he commented: "I like the player, but that does not mean we will buy him."
"The player is under contract at Everton. If we want to buy a player, we need first the agreement of the club," he said.
