"Atletico Madrid" has complained to UEFA about London's "Arsenal" for failing to provide its players with hot water after training at the "Emirates" stadium.
Idman.Biz reports that the Spanish team's players were unable to shower after training.
Although the club informed stadium staff about the problem, their requests were ignored. The players were forced to return to their hotels in central London.
"Arsenal" and "Atletico Madrid" will face each other on October 21 in the 3rd round of the Champions League.
After two Champions League matches, "Arsenal" has six points and is in fifth place. "Atletico Madrid" is 10th with 3 points.
