Modric is the subject of intense interest from Real.
"It is difficult to know how he will react when he arrives," former Real star Jarni told AS. "We must see where he is going to play and what Mourinho thinks of him.
"Whether he will be a starter or not, or if he [Mourinho] will want to rotate him. All that must be taken into account because Madrid have quality players.
"What I will say is that his way of playing and seeing football matches ties in well with Madrid and the Spanish League.
"He's a very humble guy, with his feet on the ground and, as a player, he has a lot of quality. Luka has the profile of a Madrid player. I think he has an extraordinary quality.
"If confirmed, his move will raise the level of team play. It seems a wise move on the part of Madrid."
