Ruud van Nistelrooy's joy at finally returning to action has been quickly dented by the news that he will now be sidelined for six weeks due to another injury sustained in Sunday's 5-0 hammering of Xerez.
Van Nistelrooy, 33, ended his lengthy injury absence when coming off the bench on Sunday to score his first goal since October but injured himself in the process, sustaining a thigh problem.
An MRI scan has revealed a damaged left thigh muscle and Van Nistelrooy is facing up to a prolonged spell on the sidelines.
Real opened the scoring within 60 seconds at the Bernabeu through Cristiano Ronaldo and the world-record signing from Manchester United added a second for his sixth goal in four games this season.
Karim Benzema and Guti were also on target as Manuel Pellegrini's side secured the 5-0 victory they needed to replace arch rivals Barcelona at the top of the Primera Liga.
