"He has an eye to catch young players that he wants in the future, and that is something special," Cesc told CNN. "I have always been grateful for what he has done for me, what he has done for the club and I feel very lucky to be working under him."
The midfielder also admitted playing in the Premiership was always exciting - particularly compared to the Spanish Liga.
"Whenever you watch a football game here you can see the passion," he said. "Even if the two lowest teams in the league are playing you can feel the passion. They always try to go forward, even if the game maybe technically is not the best you can feel they go to win. In Spain everything is slower and sometimes it takes 20 minutes to see something happen. But of course technically the Spanish league is very, very good."
