Wolverhampton Wanderers winger Helder Costa has emerged as a target for Arsenal and Chelsea, according to reports.
The 23-year-old permanently joined the Championship side in January for a club-record £13m after impressing on loan from Benfica.
Costa shot to prominence earlier this season with a thrilling display when Wolves won 2-1 at Liverpool in the FA Cup, which has supposedly led numerous top-flight clubs to take an interest in the player.
According to The Mirror, scouts from both the Gunners and the Blues were at Wolves' 1-0 win over Rotherham United at Molineux, where they saw Costa miss a first-half penalty.
Jorge Mendes, Costa's agent, is also said to be in conversation with a number of major clubs in England and elsewhere over a potential £20m transfer for the player.
