When David Moyes took the reigns at Manchester United this summer from his Scottish compatriot Sir Alex Ferguson, many questioned his inexperience in Europe as a major worry.

What worry? The new manager has eased his way into the last 16 of the Champions League with Wednesday's 5-0 demolition of Bayer Leverkusen. 

With United 2-0 up  at half-time, the match was there for the taking but one must wonder what Moyes said to his team at the break as they came out even better in the second half.

As United wore the Germans down, Ryan Giggs was still running proceedings until the last minute.

A tough game was coming, they said. United's shaky midfield is a problem, they said. Giggs is too old, they said. With no doubts that United must bring reinforcements into the midfield in January if they are to challenge on all fronts, the other two statements were completely obliterated after such a dominant performance.

After pundits had declared their worries about Giggs before the game,  they were left red-faced after one of his best performances in recent memory.

Many United fans will struggle to remember such a dominant performance in recent history to compare to last night's demolition of Leverkusen. Not only in the Moyes era, but also last year this United team struggled to score many goals when they were dominating the opposition. Games such as Swansea and Tottenham away were draws that could have been wins if they could have scored more than once.

We mustn't get carried away one impressive win. It has been a long time since United have put a team to the sword in such a manner and to see it done to the second team in the Bundesliga is a pleasure after such a fluctuating start to the season for the Red Devils.

With Spurs to come on Sunday, Moyes' team selection will be pivotal. After last night's performance, it is impossible to ignore the talented Shinji Kagawa after he excelled in his preferred position.

Although Kagawa was a star last night, the United manager will have a headache once Robin van Persie comes back from injury, as Kagawa is occupying Wayne Rooney's spot. With Kagawa proving to be ineffective on the left wing, Moyes must find a way to accommodate all three players in team.

We've already seen how Van Persie and Rooney have clicked in games under Moyes, but if he can add Kagawa into that mix, United will look like a threat going into Christmas before they can finally reinforce in January.
