Cardiff City boss Ole Gunnar Solskjaer says beating the drop would be the greatest achievement of his football career.
Solskjaer believes it would "definitely be a bigger miracle" than Manchester United's epic 1999 Champions League final triumph if Cardiff can avoid Barclays Premier League relegation.
"If we stay up it would definitely be a bigger miracle than Barcelona in 1999," he said.
"That night it was possible, and in football anything is possible. So we need to give ourselves a chance in front of our fans against Chelsea.
"It takes belief, togetherness, a team that goes the extra mile, and a hero stepping forward and doing something magical."
