The Croat came close to signing for the Serie A outfit during the summer only to fail to agree terms.
Rodgers clearly sees the smooth centre-half as a key figure in his plans and warned: “I think they have probably seen how well he’s been doing.
“He’s very much a part of what we’re building here.”
Rodgers looked back at the win over a hard-working Jags side at a rain-lashed east end of Glasgow and added: “That was the 41st game we’ve had which is a phenomenal amount.
“We play in a way that has a systematic approach. If one players comes in he understands his function in the team.
“There’s no way I can play all the players in every game. They have international games on top of that, so you just can’t do it.
“At times, you’re going to use a wee bit of fluency, but you see other characteristics in the team. There’s spells of great football, great possession, creating chances.
“We should have scored more goals to make it calmer, but still having that mentality to win is very, very important.”
