The agent of Romelu Lukaku, Paul Pogba, Zlatan Ibrahimovic and Henrikh Mkhitaryan could be the key to Marco Verratti's transfer to Manchester United.
The Italian dumped his former representative to recruit super-agent Mino Raiola earlier this month.
Barcelona are strong favourites to sign the 24-year-old but Jose Mourinho is keeping a close eye on the situation.
Meanwhile, former Paris Saint-Germain manager Laurent Blanc believes the player will not be sold this summer.
"I do not know what it is going to happen with Verratti," he is quoted as saying by FourFourTwo.
"Marco Verratti is a very important player for PSG.
"He has many qualities and PSG will do everything they could to keep him. It will be difficult for Verratti to move."
