Olympiacos and Grêmio are in ongoing negotiations for the transfer of 18-year-old central defender Luis Eduardo Guedes de Souza. Grêmio has rejected a €4 million offer from the Greek club for the player, whose contract is valid until May 2028. A potential agreement could be reached for approximately €4.5 million. A representative from Chelsea also observed the defender at the U17 World Cup. If Olympiacos completes the signing, it is likely the player will then be loaned to Rio Ave. The purpose of such a loan would be to allow him to gain match experience, develop, and adapt to European football. However, a loan will only be considered after the transfer from Grêmio is resolved.
