Bayern Munich coach Pep Guardiola has lauded Thomas Muller and believes the Germany forward will only get better in the years to come.

Muller has netted five goals in three Bundesliga appearances this term, and also scored three goals in two matches for his country during the international break.

Guardiola feels the versatile attacker still has room for improvement, though, and has warned that Muller's best is yet to come.

"Muller has a lot of quality. His biggest strength is his optimism and opportunism," Guardiola said at a press conference on Friday.

"He has an eye for goal. And he is still young. He will only get better."
