And what a spectacular debut it was;
BBC Sport said:
onathan Woodgate suffered a torrid Real Madrid debut, scoring a spectacular own goal and then being sent off against Athletic Bilbao.
In the first half Woodgate, 25, stooped to clear a Joseba Etxeberria shot only to head the ball past Iker Casillas.
Woodgate was red-carded on 65 minutes after picking up a second yellow card.
Despite Woodgate's sending off Real went on to comfortably beat Bilbao 3-1, with goals from Brazilian Robinho and a brace from captain Raul.
Woodgate's first yellow card came when he lunged at Bilbao midfielder Carlos Gurpegi just before the interval.
The second booking was for a foul on Etxeberria.
Injury to Ivan Helguera and a suspension for Sergio Ramos had allowed central defender Woodgate to make his debut over a year after joining Real from Newcastle in a £13.4m move.
The former Leeds United player had not started a competitive match since tearing a thigh muscle in a Premiership game against Chelsea on 25 April 2004.
He had been due to make his debut for Real last October but suffered a recurrence of the injury in a training game.
Woodgate did make a brief appearance for Real in the final five minutes of a pre-season match in August.
