Former Liverpool and Tottenham football chief Damien Comolli says PSG need to be clever over their plans for Grzegorz Krychowiak.
The Poland midfielder is this season on-loan at West Brom, where he has battled for consistency.
However, Comolli told L'Equipe: "PSG can imagine recovering some €10 million in this operation, Krychowiak remains a good player who still has a market in France, Spain or Italy.
"The best strategy would be to opt for a loan with an option to buy so that he strengthens his value.
"Because in this summer market, Krychowiak is only worth between €8-10 million."
