€80m World Cup star drops major hint over future amid Man United and Chelsea interest

The Portuguese club will certainly be worried about the situation. They will not want to lose a key player like him, but his recent comments will fuel further speculation surrounding his future.

The 26-year-old has proven himself in Portugal, and this could be the ideal time for him to take on a new challenge. Chelsea and Manchester United are among the biggest clubs in the world, and the opportunity to play for them can be hard to turn down for most players.

That said, the defender has a €80 million release clause in his contract, and no club is likely to pay that kind of money for him.
