Jose Mourinho has got a problem on his hands because it can be hard to stay humble when you crush Champions League opposition like this away from home. Manchester United have not played with this sort of panache in Europe for years. The Portuguese insisted the only way his side can prolong their excellent start is if they stay grounded, remain aware of their limitations and focus on the fact successful teams must do the ugly things before they get anyone to admire their achievements. It was a very deliberate message before Unitedâ€™s Champions League clash with CSKA Moscow, designed to remind his players that dogged 1-0 away victories like the one against Southampton last weekend are the real makings of champions. He need not have bothered for this one. CSKA entered the competition this year with a burgeoning reputation, but they were the ones humbled.
