Manchester City will have to fork out in excess of €50 million (£45m/$56m) to land the signature of Milan midfielder Ismael Bennacer - according to Calcio Mercato.
Paris Saint-Germain have also been credited with an interest in the 22-year-old, but his current employers have no plans to sell a prized asset for a cut-price fee.
Bennacer has featured in 25 games for Milan this season, and still has four years left to run on his current contract.
