Polish stopper kept Manchester City at bay on Sunday...
Following a string of fine saves, Fabianski managed to keep a clean sheet against Manchester City on Sunday, which has started to erode memories of the 25-year-old's mistakes last term.
In his post-match press conference, Wenger admitted that Fabianski could displace Almunia as his first-choice goalkeeper.
“I don’t say that definitely he will be No. 1 because you always need the freedom to change when it is really needed. But look at his performances. You can’t fault him at all,” said Wenger.
“From game to game he shows what I see in training. In our job, sometimes, you have to be prepared to fight a bit against opinions.
"It is easier for you when you know the player has the talent and I believe he has the talent."
Wenger also hailed the contribution of Samir Nasri, who notched his seventh goal in seven games and also set up Nicklas Bendtner’s late third.
“He is becoming more efficient,” said Wenger. “I think as well he has become stronger physically. You judge a player what he does with the numbers. Today he had a goal and an assist.
“He can run with the ball, is quick and is a clinical finisher now so I believe we have a great player. At 23, you are just at the start at the top level.”
