Lassana Diarra has given a timely boost to Real Madrid ahead of their clash with Sevilla after returning to training on Friday.

This match-up with the in-form Sevilla team has been dubbed Real's biggest test of the season so far.

Sevilla have been a free-scoring side with Brazil international Luis Fabiano leading the charge.

In contrast, Real are still sweating over Cristiano Ronaldo's fitness and they will delay naming him in the first-team for as long as possible.

Diarra's return will be good news for Real. Alvaro Arbeloa and Christoph Metzelder have also rejoined training, according to Madrid's official website.

Sergio Ramos, Kaka and Guti were all also back in full training.
