United could have a problem on their hands, Nani and Ronaldo have pulled out of the Portugal squad due to injury.
Nani has pulled out of the squad because he has pulled a muscle in his right leg. The man who has won United games this season Cristiano Ronaldo has been feeling pain in his left leg.
United have not said how serious these injuries are but with important matches coming up, i really am hoping that their not serious at all.

The Portugese doctor Jones said this:
"We proposed to coach (Luiz Felipe Scolari) that the players be released from the squad and he accepted,"

So, if Ronaldo is out for a bit, could it be a disaster for United?
