PSV Eindhoven are counting on a club record sale for Hirving Lozano this summer.
The Mexico international's minders are in contact with Barcelona, while Everton, Real Madrid and Manchester City have also been linked this past week.
Eindhovens Dagblad says along with Barca, new Everton sports chief Marcel Brands has also made contact with his father about a move away from Eindhoven.
Having sold Lyon star Memphis Depay to Manchester United in 2015 for €34m, PSV management are expecting an even bigger price for Lozano.
The Dutch giants are demanding an initial €40m to sell the midfielder.
