Luis Guilherme was made official this Sunday as Sporting's first winter reinforcement and confessed to being “very happy” to arrive at a “huge club”. «It is a very famous club, not only in Portugal, but throughout the world. Everyone knows Sporting and knows how great the club is. I'm very happy to be able to represent this shirt", said the Brazilian player, speaking to the Lions' media. The former West Ham man also revealed that he spoke to Mateus Fernandes before heading to Alvalade. «Matthew Fernandes always spoke very highly of Sporting, the structure and the environment. When I told him I was coming here, he was very happy and wished me all the luck in the world.” The 19-year-old player, who was launched by Abel Ferreira in the Palmeiras first team, also gathered some impressions from the Portuguese coach. «He called me, spoke very good things about the club and wished me luck. He was the one who launched me professionally at Palmeiras and I can only thank him for everything.” «Adaptation will be easier because you speak Portuguese. Some words are different, but overall I can understand. I hope to adapt as quickly as possible to help my teammates win titles", he further stated. Signed for 14 million euros (plus three million for goals), Luís Guilherme signed until 2030 for Sporting and was shielded by a release clause of 80 million euros. The young Brazilian has only played five games for West Ham this season.
