Former Inter Milan goalkeeper Sebastien Frey sees Yann Sommer as the club's No1 for several years into the future.
Monza keeper Michele Di Gregorio is being linked with Inter.
But Frey said on TV Play: "For a couple of the year that starting place will go to Yann Sommer, I wouldn't make this change now.
"The Monza goalkeeper is deserving the attention of many big clubs, it is right that he has the opportunity to make the big leap and possibly play in a big club.
"The boy has great room to continue improving."
