Further setback for Lucas Barrios

Lucas Barrios has suffered a setback to his return after straining a muscle and injuring his back in Monday’s training.

The Paraguayan striker received a pain-killing injection to help his back. It is not yet known whether Barrios will travel with the rest of the Borussia Dortmund squad for the Champions League game with Olympiacos midweek.

The defending Bundesliga champions suffered an additional injury problem as right-back Patrick Owomoyela tore an adductor muscle against Werder Bremen at the weekend and will definitely miss the trip to Greece.
