Bayern Munich winger Arjen Robben says too much harmony can sometimes have a negative impact on a team.
Bayern have started the season with a 100 percent record, registering five consecutive wins in the Bundesliga and opening their Champions League campaign with a victory over Valencia.
Yet despite their exploits in bagging maximum points so far, Robben warned his team-mates not to go overboard with the feel-good factor in the dressing room and not hold back in making their feelings known.
“It is important that … sometimes there are clashes between team-mates,” he told Sport 1.
“We need each other to tell the truth, and this is not always a positive.”
Jupp Heynckes’ side will look to extend their winning streak to seven when they entertain Werder Bremen on Saturday.
