Ole Gunnar Solskjaer has revealed he injured himself during his celebration after scoring the winner in the Champions League final in 1999.
The now Manchester United manager scored in injury time against Bayern Munch at the Nou Camp in dramatic fashion to lift the trophy.
Solskjaer slid on his knees and was asked whether that celebration caused his knee injury that let to his retirement in 2007.
The United boss told ESPN FC: 'That's not true. I did get injured and I did tweak my medial ligament.
'It was nothing to do with my injury but I missed two or three weeks and a couple of internationals for Norway but it was worth it. The celebration was worth it.
'I've seen [the goal] so many times. I cannot remember exactly what I felt because I was so focused on my job. I think it was bigger for everyone else around. I just did my job as a striker, something I'd done so many times before.
'It was just being in the right position at the right time.'
The Red Devils were 1-0 down in the final before Teddy Sheringham scored in the 91st minute and Solskjaer scored two minutes later.
The United manager will be taking his side to the Nou Camp 20 years on from that final, on Tuesday night.
The Red Devils face Barcelona in the second leg of their Champions League quarter-final tie and will have to overturn a 1-0 deficit from the first leg.
