West Ham is preparing to sell their 19-year-old Brazilian winger, Luis Guilherme, in the upcoming summer transfer window. Flamengo has expressed active interest in acquiring the player. In addition to Flamengo, Galatasaray and Shakhtar Donetsk are also keen on signing the talented young winger. However, a transfer to Shakhtar Donetsk appears unlikely due to the high demands set by Guilherme's agents, which make a move to Ukraine improbable. Despite the interest from several clubs, West Ham expects a competitive bidding process but remains doubtful about recovering the €23 million they invested last year to purchase Guilherme from Palmeiras.
