Sevilla are set to be without winger Diego Capel for around a month after the winger injured his groin while on international duty with Spain.
The 20-year-old wideman has returned to the Sanchez Pizjuan after picking up the problem while training in the build-up to Spain's World Cup qualifying double header with Estonia and Belgium.
Capel is now likely to miss forthcoming La Liga games against Almeria, Malaga, Real Valladolid, plus Uefa Cup ties with Stuttgart and Standard Liege.
Sevilla's problems have been compounded by an injury to Capel's Brazilian understudy, Adriano Correia.
Meanwhile, Capel's departure from the national team squad has led to a late call for Liverpool winger Albert Riera, who missed out on a place for the European Championship finals last summer.
The former Espanyol wideman said after linking up with Vicente Del Bosque's squad: "I came as soon as I could because to be called up to the national team is a reason to be happy and enthusiastic.
"I was angry not to be in the European Championship squad, because I was convinced that they were going to have a great competition.
"But to feel sorry for yourself and look to the past doesn't do any good and now I have to try to be in the next tournament."
While Capel prepares for a spell on the sidelines, Real Madrid stalwart Guti is confident of being fit to face Atletico Madrid in next weekend's derby.
Guti has been out of action since suffering a thigh muscle injury during Real's 2-0 victory over Racing Santander on September 21.
However, the former Spain international is confident of being fit for the trip to the Vicente Calderon on October 18.
"I'm much better after the injury. At first I had to rest completely, but I'm almost recovered," he claimed. "Next week I will start to train with the team and I will be ready for the derby.
"For a Real Madrid player, facing Atletico is one of the most important matches of the season."Reuse content
