"In England everybody always find the hair in the soup, as we say in Germany," he said after the 2-1 win at Stamford Bridge.
"Against the other teams we have a good record against top flight teams, but we are imporiving against teams which you would say are not able to be champions.
"We were happy with the start to the season, playing away to all top teams and we get 10 points so everything is good at the moment."
