Manchester United striker Wayne Rooney has revealed he thought he'd broken bones in his foot again after suffering a late challenge during victory at Porto this week.

"For a couple of minutes, I feared I'd done my metatarsal again," he said. "I've not had the best of luck against Portuguese teams.

"I did my metatarsal [against Portugal] in Euro 2004, I got sent off against Porto in pre-season and got a three-game ban and before that I got sent off against Portugal in the World Cup in 2006, but my foot is OK now."
