Mönchengladbach - Borussia Mönchengladbach midfielder has been forced to take a break from pre-season training due to injury.

The Venezuelan playmaker picked up a minor strain during the the five-time champions' 2-1 friendly victory over Celtic FC last Friday. Arango had joined up with the squad late due to international commitments with his country at the end of last season. The 33-year-old is the only member in coach Lucien Favre's squad considered doubtful for Sunday's DFB Cup first round match away to SV Darmstadt 98.
