The two teams meet on Sunday.
"We have a good relationship, very good. Usually during the summer we have dinner together. I hope he speaks very well about me as a coach, not as a friend!
"Usually we learn from Arrigo Sacchi. Arrigo is always with us, so it's very interesting to speak to Arrigo.
"It is interesting when you can listen to Arrigo speaking about football. I think he is father of our football, the football of Guardiola and my football, so for us it is very important to listen."
