Premier League clubs have been frightened off of Hulk by Porto's asking price.

The Sunday Express says Porto have rejected offers of £40million.

Manchester City, Tottenham and Chelsea are tracking the powerful Brazil striker, 25.

But Hulk's agent Teodoro Fonseca said: "Five clubs have offered £40m and Porto didn't accept it.

"Only if someone meets the £88m buy-out clause - if it happened, it couldn't be blocked."
