Getting the best out of Wayne Rooney and more - Marouane Fellaini might prove to be the ace of the pack

And finally, there is the bit on Shinji Kagawa and how he ultimately proved to be a vital cog in United’s attack, even though he did not have a direct contribution to any of the 4 goals.

The Japanese international played it smart for the hour that he was on the pitch, taking up some interesting positions, predominantly between Giulio Donati, the right back and Omar Toprak, the right sided centre back.

As Kagawa operated between the lines of defence, he found the odd pocket of space and made good fist out of it – as seen when he put Van Persie on goal in the first half.

Another interesting observation was the drifting of Van Persie towards the left when Toprak took charge of Kagawa, thereby trying to create a 2v1 with Evra against Giulio Donati.

Though the Japanese international eventually ran put of steam during the hour mark, there were encouraging signs, and those can only amplify as he gains fitness during the course of the season.

Given that the footballing calendar has just started to gain momentum, David Moyes may well have to approach a dynamic approach to ensure United do not earn the tag of a predictable team.

He may well have to tinker and tune and play according to the situation, but with the squad at his disposal, rotation may not be the most difficult among his list of priorities.

For starters, Tuesday night was certainly impressive and commanding by the Red Devils against their German hoodoos.
