Manchester United and Barcelona have plenty of history with the likes of Bryan Robson and Romario headlining previous meetings.
Manchester United will on Wednesday meet Barcelona in the first leg of the Champions League quarter-finals at Old Trafford, evoking memories of some wonderful European encounters.
The two heavyweights first met in 1984 with an incredible two-legged tie in the Cup Winners' Cup setting the benchmark for what was to follow.

Still talked about by United fans of a certain vintage as one of the best nights in the club's history. Having lost the first leg 2-0 at Camp Nou, United were heavy underdogs but a Barcelona side containing Diego Maradona and Bernd Schuster were overwhelmed amid a frenzied atmosphere at Old Trafford. Bryan Robson scored either side of half-time to level the tie on aggregate before Frank Stapleton popped up with the winner eight minutes into the second period. United could not go all the way, though, losing to Juventus in the last four.
