Nani, 25, has been struggling to shake off a foot injury he sustained in last week's friendly defeat to Turkey and he trained away from his team-mates on Friday.

However, coach Paulo Bento will give the Manchester United star a final opportunity to prove his fitness ahead of the crunch clash with Germany in Lviv.

"Nani will train again and then we will evaluate this injury that he had on the same part of the body as before," Bento said. "We'll see after the training how we proceed with him ... the only player we are not sure about is Nani."

Bento is keen to treat Nani carefully as a similar foot injury forced the winger to miss two months of action for his club earlier this year.
