Giovanni Trapattoni is confident Robbie Keane will be fit to lead the attack when the Republic of Ireland travel to Bulgaria for their crucial World Cup qualifying clash.

The Tottenham striker sat out training on Tuesday with a foot injury but is expected to line up against his former White Hart Lane team-mate Dimitar Berbatov and Co in Sofia on Saturday.

"It was just as a precaution, he has some inflammation under his foot, it's nothing serious and he will be fine for Saturday," said Trapattoni.
