Difficult tie here now Vidic and Rooney are not playing!
It will give Barcelona a bit more confidence knowing the defensive lynchpin and the talent of Rooney won't be against them.
I am leaning towards a nervy opening half which will see 2 teams scared to venture too far forward in case of being counter attacked and conceding a goal!
My certainty for this game is
draw at half-time! 10/11 Paddypower.
The value bet I'm going to go for mainly because of what is up for grabs here a final place in The Champions League in Moscow:
Man Utd to win on penalties 25/1 Paddypower Barcelona to win on penalties 25/1 Paddypower 
P.S. I hope Man Utd win it as it would be brilliant to have 2 premiership teams contesting the final and the hope that all fans who turn up at Moscow have a party atmosphere and enjoy the occassion and not what most people fear of running battles and shaming the English game!
