Sevilla and AC Milan have both reportedly joined the race to sign Enner Valencia this summer.
West Ham United were believed to be closing in on the Ecuadorian forward, but they are likely to face competition for the 25-year-old.
According to The Times, Valencia could delay his move to Upton Park as he is open to the possibility of moving to Sevilla or Milan.
Valencia impressed with his performances for Colombia at the World Cup, and his club Pachuca appeared to be resigned to losing their striker this summer.
A bid of £12m was reported to have put the Hammers in pole position, and their rivals will likely need to offer at least the same to be recognised as serious contenders for his signature.
