Bayern Munich icon Sepp Maier expects new arrival Arturo Vidal to see plenty of red cards in the years to come, but believes the Chile international will prove to be a fine addition for the Bundesliga champions.
The Bavarians lured the 28-year-old away from Juventus last month after selling Bastian Schweinsteiger to Manchester United and Maier feels the midfielder adds something to the team Bayern were previously missing.
"Vidal will get a few more red cards than Schweinsteiger got. You have to take that into account," Maier told Bild.
"But someone's got to do the dirty work in midfield and make the occasional foul. You need players like him if you are to achieve anything.
"It's alright for the rest of the team to be nice guys, but there always has to be one guy who is not afraid to stick his feet in. And Vidal is just that guy."
Maier also had his say on the future of Mario Gotze, who has been heavily linked with a summer exit, and has urged Bayern to hold on to the Germany international.
"You simply cannot sell Gotze. A young player like him needs time. Bayern will have to be patient and I have no doubt he will eventually find his feet.
"Bayern should not sell him. It's not like they need the money..."
