Veh watched on as his side became the latest victims to Bayern's impressive form on Sunday, with the champions running out comfortable 5-0 victors at the Allianz Arena.
"We did all right in the first half an hour, but Bayern are in a different league," Veh told reporters.
"I've never seen a team as strong as Bayern in the Bundesliga. It's unbelievable, you have to admit it. The scoreline, though it was comfortable, is nonetheless acceptable."
Bayern's next match comes against Nuremberg on Saturday as they look for a 12th league win in a row and a 45th consecutive match without defeat in the Bundesliga.
