Scouts from the West London club reportedly watched the Legia Warsaw winger last weekend.
Delegates from the West London club watched the Polish giants smash Pogon Szczecin on Sunday, in which the 25-year-old managed a full 90 minutes.

Rangers boss Jimmy Floyd Hasselbaink, who replaced Chris Ramsey at Loftus Road in December, has a difficult job next season. Not only must he do his best as far as promotion goes, he must do so relying on bargain-basement playing due to the R's shift in transfer policy.
Hasselbaink's side finished 12th in the Championship this past season, 14 points off a playoff position.
