Monza GM Adriano Galliani is adamant Valentin Carboni won't leave this month.
The Argentine midfielder is on-loan at Monza from Inter Milan and has attracted interest from West Ham.
The Hammers have failed with an opening offer for €14m.
And Galliani says West Ham should forget about trying again this month as their loan deal is watertight.
He explained: “It's not happening. Bid from West Ham? He's staying at Monza for sure."
