Manchester United boss Sir Alex Ferguson is treading carefully with Cristiano Ronaldo's comeback.

Tonight against Champions League rivals Aalborg, Ronaldo is expected to start even though he had heavy strapping wrapped around his suspect ankle before training yesterday.

Ronaldo was out of action for three months after having it operated on following Euro 2008.

The strapping may be purely a precaution but it is clear there are still concerns over the Portuguese winger.
