He said: “Klopp was a very good coach.
“Out on the pitch his mentality is to win, off it he was very friendly with the players and I'm very happy I had two years with him.
“Auba and Mikki were very important in me joining Arsenal.
“It is like something more than friends.
“We were together in Borussia and they are both very good players.
