Arsenal are eyeing Paris Saint-Germain defender Mamadou Sakho.
William Gallas looks increasingly likely to leave the Emirates this summer after failing to agree a new contract and PSG are keen to take the 32-year-old back to Ligue 1.
Sakho would have no complaints swapping Europa League at the Parc des Princes for the Continent's top competition with the Gunners.
He said: "My agents have received requests from foreign clubs which they must analyse with PSG. I do not know if I'll stay, I must feel we can make progress next season."
