I was always harsh on myself as a player and I am the same as a coach, but it's the only way I know how to improve.
Everyone says Cristiano Ronaldo or Lionel Messi, but I would have love to have played with Luka Modric. I think he's an incredible player, really strong mentally and a pure footballer.
It's important that everyone rows in the same direction because I need all my players, those who don't get much playing time too.
There have been some stressful months since taking over at Milan, but I think I've improved a lot in terms of character.
