"Ozil is like the team in that he had an outstanding first half that had everything you want to see from a great player. There was individual skill, team play, finishing and final ball. Just sit there and enjoy it.
"I loved him when he was at Madrid, I thought he was great there. We are lucky to have got him. He enjoys playing football and enjoys playing with his team-mates - he's integrated very quickly.
"We got so much stick at the start so now I'm cautious, but of course he's given belief to everyone around the club. Belief is part of success in football."
"At home that first half is one of the best halves we've played in a long time. It was a very enjoyable game with a fantastic first half, played at a great pace. There was belief and authority in our game. The finishing was great.
"The second half was more cautious but in patches when we went forward you could see the third goal was there.
"Napoli suffered in the first half and the chased the ball a lot. That took a lot of energy out of them. They didn't give up, but they were tired. They're a very good team, that's why the trip to Naples will be difficult and a big fight.
"We play Dortmund next and the group looks very tight. The key game will be us against Dortmund in the next game."
