Manchester United faced the daunting task of overturning a 2-0 deficit when Barcelona arrived for the second leg of their European Cup Winners' Cup quarter-final clash in March 1984.
But inspired by an incredible atmosphere at Old Trafford, Bryan Robson dragged the Reds back into the tie with a courageous, ubiquitous display against Diego Maradona and co.
The skipper scored twice before Frank Stapleton smashed the winner as Ron Atkinson’s side completed a remarkable comeback. And Robson admitted his lion-hearted performance was driven by a sense of duty from the first leg.
"The first game hadn’t gone to plan and I blamed myself because I’d had a couple of really good chances, so I just felt I owed the lads," Robson told ManUtd.com. "The second leg went really well for us. We said we needed to try to get a goal in the first 20 minutes; we did that and went on.
"And the fans gave us so much energy – it was the best atmosphere I ever experienced at Old Trafford. A great win and great memories."
At full-time, hundreds of jubilant fans ran onto the pitch and Robson was carried shoulder-high. "My name was being sung and my back slapped till it hurt," he said. "But it was one of those nights you dream about and treasure for the rest of your life."
