UNAI EMERY backed Arsenal star David Luiz to get back to his best ahead of their derby clash with Tottenham.
But Emery expects Luiz to be firing on all cylinders for the first North London derby of the season.
Luiz, 32, avoided picking up a second yellow at Anfield as Salah skipped past him to score his second — an act that has not gone unnoticed by boss Emery.
The Spaniard said: “We can speak about some faults with one player.
“But we can also talk about some good decisions and very good actions from him in that match.
“For the penalty he received a yellow, so if he had made a foul on Salah for the next goal, he would have a second booking.
“So he was intelligent and we can speak about his positive decisions.
“It is not easy for him. He only came to us three weeks ago and the adaptation has been very quick.
‘VERY AMBITIOUS DECISION’
“But I am very happy with him because he made a very ambitious decision to come to Arsenal.
“He wants to do something important to help us and I want that mentality.
“I want to transmit his ambition to the other players, then we can be competitive.”
German ace Mesut Ozil has been linked with a move away this summer after disruptions on and off the pitch.
Ozil, 30, still has two years of his Arsenal deal to run but has not featured this season.
He missed the opening-day win at Newcastle because he was traumatised by an attempted car-jacking and was ruled out of the home win against Burnley with a virus.
But Emery insists the club’s highest-paid player is available on Sunday — and denied Ozil is on his way.
He said: “We are not speaking about the possibility Mesut could leave.
“This week he is training well and progressing physically. I think he’ll be available for Sunday.
“We have finished our transfer window in England and in Europe it’s going to end on Monday.
“We cannot sign another player but some other players could leave.”
Sunday’s match could be defender Nacho Monreal’s last game for Arsenal before a potential £3m move to Real Sociedad on Monday.
