Bobadilla sidelined with ankle damage
Borussia Monchengladbach manager Michael Frontzeck was unhappy with the challenge that damaged Raul Bobadilla's ankle in Saturday's friendly.
Gladbach lost 2-0 to Premier League outfit West Ham, although it was the ankle ligament damage suffered by the Argentinian striker that Frontzeck bemoaned the most.
Bobadilla hobbled out of the match on 40 minutes after being caught and the 23-year-old is now expected to be unable to train for the next four weeks.
"At this early stage of preparations, the point of playing friendlies is to build certain elements into your game. They're actually training sessions under competitive conditions," explained Frontzeck.
Punished
"So it's very annoying to have now lost two players inside five days this week due to injuries caused by overzealous tackling in warm-up matches.
"Patrick Hermann was on the end of one in Echt on Tuesday, against West Ham it was Raul Bobadilla.
"Fouls from the side or from behind, as was the case in both instances, should actually be punished with a red card... I say to my players before a friendly that I don't want to see that sort of thing.
"I expect our opponents to take the same approach and if that's not the case, I expect the referee to take appropriate action."
