Barcelona without midfielders Sergi Roberto and Andre Gomes for a month
The true strength of Barcelona's squad will be put to the test in the next month after the club said on Tuesday midfielders Andre Gomes and Sergi Roberto were ruled out for up to four and five weeks, respectively.
Roberto, a natural midfielder who also plays as a full back, was forced off in the first half of Barca's 0-0 draw at Greece's Olympiakos on Tuesday in the Champions League with a hamstring injury.
Portugal's Gomes also ended the game with a hamstring problem even though he only played the last 15 minutes.
Barca are unbeaten in all competitions so far this season and top La Liga with 28 points from 10 games while leading Champions League Group H with 10 points. But their midfield pair will miss league games with Sevilla, Leganes, Valencia and the trip to Italy's Juventus.
