Thomas Muller has revealed that Louis van Gaal was the man that has most dramatically influenced his career. Although the Dutchman is most recently remembered for his disappointing spell at Manchester United, the German was effusive in praise for his former mentor at Bayern Munich. “When we talk my biggest influence I have to say Van Gaal,” Muller told Goal. “He threw me in the deep end. “I made my debut before he arrived, but he was the one who relied on me more continually. “For players during our active career, it is always difficult to talk about coaches – whether it is former or a current. It is difficult to say for a player who was the better coach. But I would say that my biggest influence was Louis van Gaal, because I was at the best age to be influenced.” Muller, nevertheless, rates current boss Carlo Ancelotti highly and believes the Italian can turn things around after a disappointing run of results.
