London - One image haunts Manchester United fans ahead of Wednesday's Champions League football tie against Internazionale: that of Jose Mourinho sprinting down the Old Trafford touchline, coat flapping behind him, arms outstretched, to join his players in celebration by the corner flag.
That was a last-16 game in 2004, and Porto's improbable 3-2 aggregate victory was the first English football had really seen of Mourinho.
He was brash, unpredictable, successful and, as he would later point out, very clearly "not from the bottle. A special one."
Two weeks ago, United comprehensively outplayed Mourinho's Inter at the San Siro - so much so that there was a sense of disappointment that they only managed a 0-0 draw.
