Chelsea scout Piet de Visser has had a dig at Manchester United, claiming new signing Nani may not be good enough for the Premiership.
De Visser has been asked by Blues owner Roman Abramovich to identify young talent to bring to Stamford Bridge, but has cast doubt on whether United's big-money signing can cut it in the English league.
Dutchman De Visser admits the 20-year-old midfielder has huge potential, but reckons his crossing lets him down and claims he holds onto the ball for too long.
De Visser, who recommended John Obi Mikel to Chelsea, told The Sun: "This boy is, as far as his skills are concerned, a super talent.
"He had his training with Sporting Lisbon and technically he is so good, he is almost perfect.
"But I also stress that despite all his talent he may not be right for the Premier League.
"His crosses are sometimes OK, sometimes bad.
"He dribbles too much with the ball because he wants to entertain, not because he wants to be effective.
"Cristiano Ronaldo had the same problem when he first played for United."
