New Inter Milan boss Roberto Mancini is convinced about the quality of his midfield.
The derby against AC Milan will mark Mancini's return as Inter coach.
"I think Guarin is a great midfielder who must both attack and defend. He has the goal in his blood and will be an important player for us.
"Kovacic has excellent quality and is very young. We have to expect a few errors at his age, but will work to get the best out of him. We mustn't put too much pressure on, because he cannot be the one who changes every game. Considering his role and his characteristics, we do expect plenty of goals from him. He needs to be close to the box, without forgetting to give a hand to the defence.
"Hernanes is not in great shape, so I will decide tomorrow morning who to use in that position. Of course to win you need a solid defence and it's fundamental everyone lends a hand. I will try to give a more attacking mindset to those players moving into space without the ball."
