Barcelona sweating on Sergio Busquets' foot injury

Barcelona midfielder Sergio Busquets is a doubt for the weekend's game against Athletic Club after injuring his foot in the win over Chelsea. 

Busquets was forced off early in the second half, replaced by Andre Gomes with Barça 2-0 up in the tie. 

The Catalan club revealed in a statement: "During Barça's game against Chelsea, Sergio suffered an injury to his right foot. He will have more tests to discover the extent of the injury." 

Barça will hope that Busquets, a key part of their midfield, will not be sidelined for too long with a number of important games coming up.
