Over 12,000 fans paid to watch Manchester United star Cristiano Ronaldo and his Portuguese teammates in training yesterday.

Tickets worth 15 Swiss francs (£7.38) to watch the Group A favourites at Neuchatel's La Maladiere stadium have sold out and are being negotiated on the black market at four times that price, Portuguese online media said.

Carlos Godinho, the squad's technical director, said Portugal were charging for two training sessions to help meet high costs of their participation in the tournament.

There is another open session scheduled for Sunday.

"We are the only national team that has paid training sessions, but we're also the only one that will have training in front of 12,000 people," he told reporters.
