Thomas Muller acknowledges it will be extremely difficult for Bayern Munich to emulate a trophy-laden 2013.
After winning the Bundesliga, DFB-Pokal and UEFA Champions League under Jupp Heynckes last season in an unprecedented treble for a German side, Bayern have continued to enjoy success following Pep Guardiola s appointment as coach.
Guardiola s men are top of their domestic league, lifted the UEFA Super Cup in August and added the FIFA Club World Cup title on Saturday with a 2-0 win over Raja Casablanca.
Bayern will now enjoy a period of rest due to Germany s mid-season break, and Muller believes the team can have no regrets after a superb year.
It s nearly impossible to play at the level we ve done in this calendar year, the Germany international told the club s official website.
After this win, we can go into a relaxing holiday with a clear conscience.
Reflecting on the Casablanca triumph, Muller added: Our opponents did what they could to make it a tough match. We would have liked to score another goal or two, but Casablanca didn t make it easy.
We re happy to be Club World Cup champions. It s a fairytale ending, the well-earned reward for the excellent year we ve had.
