Injury blow for Barca's Sanchez
Barcelona's Alexis Sanchez has been ruled out for four weeks with a foot injury.
The 23-year old was forced off the pitch after just 20 minutes of Chile's 3-1 friendly loss to Serbia on Wednesday, and the results from the scan have revealed that he is suffering from a sprained lateral ligament in his right foot.
If the injury keeps the attacker out of play as long as Barcelona staff fear, then it could potentially keep him on the sidelines for up to eight matches - meaning he will miss their crucial Champions League matches against Spartak Moscow and Benfica, while also a top-of-the-table La Liga clash with Atletico Madrid.
This will not be his first absence from the Camp Nou outfit, as earlier in the season he suffered from a small tear in his thigh, which kept him out for a short period of time.
Sanchez also has a history of returning from international duty with injury problems, which will not please Barcelona coach Tito Vilanova.
However, captain Carles Puyol, who missed several weeks after dislocating his elbow, could be ready to return to action against Real Zaragoza on Saturday evening.
But Sergio Busquets is suspended for this weekend's clash.
