Lukasz Fabianski insists he is ready to face Chelsea after impressing between the sticks for Arsenal on Tuesday night.
The goalkeeper, who had earned the nickname 'Flappyhandski' from some Gunners fans following a string of errors, answered his critics with two late saves, one from a penalty, as the Gunners saw off Partizan Belgrade 3-1 in UEFA Champions League action.
Since his arrival at the Emirates in 2007, Polish keeper Fabianski has taken a backseat to regular No.1 Manuel Almunia, who is himself under the spotlight following his below-par display in the shock home Premier League defeat to West Brom last weekend.
Almunia is doubtful for Sunday's trip to Stamford Bridge due to an elbow injury, meaning Fabianski could be set to keep the gloves this weekend.
Gunners boss Arsene Wenger, who has always backed Fabianski, was delighted with the Pole's performance in Serbia on Tuesday.
And the shot-stopper is keen to keep repaying the manager's faith, starting with this weekend's London derby.
"Overall, I am pleased with my performance," said Fabianski.
"I am not talking about just saves, but reading the game, coming for crosses or playing with my feet.
"Every aspect of goalkeeping is important for me, so I am pleased with my performance in general."
He added: "I am ready to play against Chelsea. I was always ready, so we will see.
"I was never really bothered by all the things said. I was always trying to focus on my job and my work.
"That is what I was always doing and that why I am grounded."
Fabianski feels the Gunners can face their local rivals with renewed confidence on Sunday following their Stadion FK Partisan triumph.
"We are playing really well this season," he said.
"The beginning was really good for us. There was a big shock on Saturday when we lost, but I think you could see against Partizan that we had learned some things from Saturday.
"The performance was much better so we are looking forward to the Chelsea game.
"It is going to be an exciting one to watch, and we are in good condition."
