According to Spanish outlet Diario AS, Manchester United and Chelsea have opened talks with Grêmio for 17-year-old centre-back Luis Eduardo, with both Premier League clubs said to be preparing formal offers. The player's contract, renewed earlier this year, reportedly includes a €60 million release clause. Despite the interest, Grêmio is understood to want to retain the defender, who is considered an important component of the club's future plans. Eduardo has attracted attention for his performances at the U-17 World Cup for Brazil, and some reports describe him as one of the quickest centre-backs in world youth football. The report from Diario AS noted that both English clubs have already made contact. For Manchester United, the significant fee for a player not proven at senior level is a potential issue due to the club's financial situation, while Chelsea's more aggressive transfer strategy could make them more willing to finalize the deal.
