Ten years on Sunday, Manchester City came to Old Trafford and won 6-1.
At half-time of Manchester United’s Champions League match on Wednesday night against Atalanta, as former stars like Paul Scholes muttered darkly in TV studios, it was hard not to wonder just how that anniversary would be marked.
Liverpool are the visitors and they have scored at least three times in every away game they have played this season.
By full time against Atalanta, it felt different. A 2-0 deficit had been transformed quite thrillingly into a 3-2 victory for Ole Gunnar Solskjaer’s team.
