He also insinuated that the Red Bulls fitness staff was responsible for a rash of hamstring injuries.
"We've been having eight or nine hamstring (injuries) in three weeks. So clearly something's happening. I don't know (what's happening). I'm not the fitness coach. We've been doing what we've been told."
Coach Hans Backe acknowledged the problem.
"Five or six (players) have had tight hamstrings. so we have to check that, definitely," he said. "I have to sit down and figure out why we have that."
