The 48-year-old has already produced a number of entertaining moments since moving to England from Germany, while he recently clashed with West Brom manager Tony Pulis in a fiery 2-2 draw.

"I would like to be cooler but I am pretty emotional," he told reporters.

"Sometimes I laugh more than I should. Sometimes I get more angry than I should."
