According to A Bola, the transfer of Luís Guilherme to Sporting is confirmed, and the agreement with West Ham has been closed. The winger is set to arrive in Lisbon within the next few hours to have medical examinations and sign a contract for four-and-a-half seasons, which will be valid until June 2030. An official presentation for Luís Guilherme is scheduled for the beginning of the week. The acquisition cost for Sporting is €14 million, with the potential for this amount to rise to €17 million contingent on the achievement of objectives, which account for up to €3 million in bonuses. Should his registration be formalized by Tuesday, it is possible that Luís Guilherme will be available to Rui Borges for the League Cup semi-final match against Vitória de Guimarães.

According to A Bola, Luís Guilherme is expected to become the first winter signing for Sporting. The club will invest 14 million euros immediately to sign the 19-year-old Brazilian winger from West Ham, in a deal that may increase by 3 million euros in bonuses to a total of 17 million euros. An agreement has been reached and the process is in the final stage of exchanging documentation.

The release clause is expected to be approximately 80 million euros, and West Ham is also expected to secure a percentage of a future sale.

According to ESPN, Sporting and West Ham finalized the last details of an agreement for Luís Guilherme in the last few hours. The Portuguese club will pay the English club approximately 20 million euros, including fixed and variable amounts. The young forward, who was also a target for interested parties in Brazil, chose Sporting primarily because of his desire to remain in Europe and ruled out returning to the country.

Fabrizio Romano reports that Luis Guilherme will leave West Ham United for Sporting Portugal, with the final details currently being completed. According to Romano, an agreement has been reached for a permanent transfer. It is reported that the transfer will earn West Ham seventeen million euros, including bonuses. West Ham United has secured a resale percentage.

According to A Bola, Luís Guilherme, a 19-year-old winger from West Ham, is close to joining Sporting. The value of the deal could reach €20 million. Luís Guilherme is expected to be an immediate reinforcement and a prospect for the future.

According to A BOLA, the Sporting administration is considering Luis Guilherme, a 20-year-old winger from West Ham, for a potential reinforcement in January. Sporting's intention is to sign the player on a permanent basis for a fee between €15M and €18M. The English club, however, only wants a loan deal because they continue to believe in the potential of the player, whom they signed from Palmeiras for €23M in July 2024. Negotiations are in progress. The specialized site transfermkt states that Luis Guilherme's current market value is €10M. For the player, the prospect of playing in the Champions League and the opportunity to develop at a club that contends for titles are attractive. The process is not dependent only on his will, since many aspects still need to be negotiated between the two clubs. He has been identified by the Sporting scouting department for a long time, and the transfer possibility emerged due to his limited usage at West Ham.

According to sources, Luis Guilherme could move to Portugal in January, and Sporting CP is one of the leading clubs to sign him. Sources indicate West Ham are willing to let him depart, preferring a permanent transfer to raise funds due to financial pressures. Initial talks were about loan options with an obligation to buy, but negotiations have moved towards a permanent sale, with a potential fee in the €18-20m range, including add-ons. Sporting CP are considered frontrunners, and sources from Portugal suggest swift progress is being made on a permanent deal. The Primeira Liga champions consider Guilherme a priority to strengthen their attack, particularly as injuries and international commitments have reduced their options in wide positions. Guilherme is interested in the move and is open to returning to a football culture in Portugal that is more familiar to him, where he believes he can regain his form and get regular playing time.

ESPN reported that Sporting has made progress in recent hours in negotiations to permanently sign striker Luís Guilherme from West Ham. Initially, discussions were for a loan with a purchase obligation, but the agreement is now close to being a permanent transfer. The Portuguese and English clubs are still aligning the transfer values, as the amount will consist of a fixed part and another based on objectives. Both clubs are confident of a successful conclusion to the deal. The 19-year-old Brazilian is receptive to the move to Sporting in January, where he could potentially arrive as a starter for the club, which is the current national champion.

Sporting is interested in signing 19-year-old Luís Guilherme and has initiated first contacts with West Ham to advance negotiations. The player is a priority target for the Portuguese club in the January winter market due to his versatility, as he can play on both wings and centrally. West Ham had acquired the attacker from Palmeiras for €23 million in the 2024/25 season, and he holds a contract with the English club until June 2029. Porto was also reportedly interested in him during the previous transfer window.
