"The two clubs haven't talked yet and that's the most important thing before a transfer goes through," said the player's agent, Rob Groener.
"The injury caused us lots of problems and there isn't anything certain yet. Inter want to be sure the player won't get worse in the future.
"However, Inter are in pole position. Marko wants to play for them but he is not desperate. Lazio are also interested but they are just one of the many clubs after my client."
