Chelsea face difficulties in completing the signing of Porto striker Hulk.

Diario Noticias says he biggest stumbling block to his move to Chelsea is a dispute about who should pay his agent for his five per cent stake in Hulk, and Uruguayan club Atletico Rentistas, who own 10 per cent.

Chelsea's hopes appeared to take a hit earlier this week when Ligue 1 side PSG made contact with Hulk's agent and suggested they would be willing to pay up to £43million, some £13m more than the Blues had opened the bidding at.

But now Hulk has revealed he would welcome a move to England over France.
