Former Udinese sports chief Nereo Bonato has warned AC Milan about losing Gonzalo Higuain.

On-loan from Juventus, Higuain is wanted by Chelsea this month.

Bonato told TMW: "It's been a complicated story from the beginning, I think Higuain was not happy to leave Juventus, but there's also Milan's unsatisfactory performance.

"And Higuain will surely be tempted by Chelsea, looking for a central striker.

"Milan need investment, they must try to enter the Champions League and it will be more difficult without the Argentine."
