The experienced defender has stressed that the Nerazzurri should turn their attention to the match again Catania again
The Colombia international has been heavily linked with a move away from Inter this winter and was on the verge of joining Juventus earlier this week in a sensational swap deal involving Mirko Vucinic.
The deal eventually fell through, though, as Inter president Erick Thohir pulled the plug on the move after fan protests.
Guarin's collapsed move has led to fear about unrest in the Inter squad, but Campagnaro has stressed that the players should focus on their duties on the pitch.
"We're trying to think about the Guarin affair as little as possible and are trying to focus on playing," Campagnaro told Sportmediaset.
"These things have nothing to do with us. We're just looking to win as soon as possible.
"Would Guarin be a big loss to the club? I don't know because I'm not sure if he's staying or going. But as I've said, we need to focus on playing."
Inter still await their first win of 2014 and have scored just once in their past four games.
