Ottmar Hitzfeld can still feel it now. Der orkan, he calls it. The hurricane.
The blast of noise from Manchester United's fans in the Nou Camp when Teddy Sheringham equalised in the 1999 Champions League Final.
His horror as the game raged out of control in three catastrophic minutes of injury-time before Ole Gunnar Solskjaer's winner ripped the European Cup from his grasp.

Twenty years on and Hitzfeld still wears a look of disbelief when he talks about it.
A master tactician who trained to be a maths teacher before becoming one of the greatest football coaches of his generation, the 70-year-old has long since given up looking for the logic in it all.
'I can't,' he replies with a gentle shake of the head when asked to explain how Bayern Munich of all teams fell apart in Barcelona that night. 'That's why we are talking about it now.' Afterwards, when he closed the door on a silent and shattered group of players, the Bayern coach wandered back into the tunnel where he embraced his old friend Alex Ferguson.
'He just said "incredible",' recalls Hitzfeld. 'He didn't actually say sorry, but you could tell he was apologising in some way.
'I've always had a strong relationship with Ferguson. There's a lot of mutual respect and we like each other as personalities as well.
'But we never talked about it again. What can you say? It speaks for itself. We knew that for one of us it was the greatest thing ever, and for the other it was the worst thing ever.
'But that moment of embracing in the tunnel, the gesture and the empathy, meant more than a thousand words.' It was the only time in seven meetings between the two men that Ferguson emerged victorious. 'I lost the wrong one,' says Hitzfeld with a smile.

He beat United home and away en route to winning the Champions League with Borussia Dortmund in 1997, and again when Bayern finally lifted the European Cup in 2001. He is among a select group of only five coaches to have won it with two different clubs.
Bayern also played United twice in the group stage in 1998-99, drawing both games 2-2. But when it really mattered, Ferguson somehow found a way to win.
It's the one result more than any other that Hitzfeld would change. Even more so than the last game of his career at the 2014 World Cup when he came within two minutes of taking Argentina to a penalty shootout as coach of unfancied Switzerland.
'Yes, of course,' he says. 'But you have to move on. You can't spend your life dreaming about what might have been.' We meet in the Swiss city of Basel just over the border from Germany where Hitzfeld has retired to his birthplace of Lorrach.
He has kept the appointment despite undergoing a minor operation at the start of this week that will prevent him from renewing acquaintances with Ferguson in the '99 reunion game at Old Trafford on Sunday.
The two men stay in touch by text message. 'I don't phone him because I can't understand him - my English isn't good enough,' says Hitzfeld through an interpreter.
Studious and quietly spoken, he was a good choice to succeed Giovanni Trapattoni as Bayern coach and act as a buffer between outspoken president
