Arsenal boss Arsene Wenger insists they're trying to land their defensive transfer targets.

Wenger says he is frustrated by the inaction.

"We are a big attraction, but if it was easy we would do it. We haven't found anyone.

"I am not the only one working on the case. It's not a supermarket where you go in and buy a defender, it's a market that is very restricted.

"Players who can strengthen the best 10 teams in Europe, you don't find many and it's the same for everybody.

"Of course we have made enquiries and then you have a second handicap of who wants to sell their best players, especially a central defender, in the middle of the season. They say, 'OK, come back in June or July and maybe yes'."
