The Spaniard, quoted in the Daily Mirror, said: "[Cazorla] is comfortable in that position, that free role. He has a lot of talent, you can see how good he is on the ball.
"We need to get him involved whenever we can because he can have a big influence.
"Lukas looked really good on the left. He was cutting in and causing problems. He had a couple of chances. We need to give them a bit of time.
"All the talk about Robin all of the time... you can get frustrated.
"Last year, [Cesc] Fabregas left. We all know what that meant. You cannot do in two games what it has taken eight years to create. It's impossible.
"Robin is obviously a really good player. He scored almost every time we played in the league last year. It's tough."
