MADRID (Dispatches) -- Lionel Messi and Luis Suarez remain doubts for FC Barcelona's next La Liga game after once again missing team training.
Messi has not played for Barca since suffering a calf injury while in pre-season at the start of August, missing most of his side's warm-up matches, as well as their three La Liga matches to date.
Those games have only given Barca a disappointing total of four points after they lost away to Athletic Club Bilbao and were held 2-2 away to newly-promoted Osasuna in their final game before the international break.
Suarez meanwhile suffered a muscle injury in the 1-0 defeat in Bilbao on August 16th and has not played since.
Although Spain internationals Sergio Busquets and Jordi Alba were able to train with the Barca squad on Tuesday after returning from international duty, neither Messi nor Suarez took to the training pitch with their companions and both continued to work alone.
Barcelona's next league game is a home match against Valencia on September 14th.
Valencia beat Barcelona in the final of last season's Copa del Rey and are likely to provide stiff opposition for a side that still has to find its feet this season. The following week will also provide no respite as Barca face a difficult Champions League tie away to German side Borussia Dortmund.
