Chelsea must move quickly to secure a deal for Porto star Hulk as the race for his signature heats up. Hulk's agent Teodoro Fonseca is heading to England for talks with at least four English clubs, but he has warned that Real Madrid coach Jose Mourinho has been watching developments.

Tottenham, Liverpool and both Manchester United and Manchester City have also shown interest in Hulk, but Fonseca has hinted that Chelsea are the 25-year-old's preferred destination in England.
