Inter Milan president Erick Thohir is pleased with the work of coach Walter Mazzarri.
Thohir admits their relationship is becoming stronger.
"On Monday we were on the bus together and I was teasing him," Thohir revealed.
"I like his energy during the game and seeing him smile often I told him that I was worried because if he smiles then the team relaxes.
"I was joking, of course, but I really wish that the group had the face for battle that Mazzarri has.
"Someone who will not relax at all, always looking for the best. That is part of his character.
"Did we talk about the defence being a back three or back four? Of course, we will use both. But certainly there is no winning formula."
