Portuguese footballing legend Cristiano Ronaldo, who has been playing for Al Nassr of Saudi Arabia since January, has said that any return to European football is a “completely closed door” for him. The 38-year-old was talking to reporters yesterday after a match at the Algarve Stadium between Al Nassr and Celta de Vigo of Spain – which the latter won 5-0 – in what was the opening game of the Algarve Trophy. “The way I see it, Europe has lost a lot of quality,” said Ronaldo.
