Thomas Muller says Bayern Munich could repeat their 2013 treble after crushing 10-man Besiktas 5-0 in the first leg of their Champions League last-16 tie.
Bayern have one foot in the quarterfinals with Besiktas facing a near impossible task for the return leg in Istanbul on March 14.
Both Muller and Poland striker Robert Lewandowski scored twice as Bayern ran riot in the second half in Germany.
“Everything is possible,” Muller said when asked whether Bayern can repeat their 2013 haul of Champions League, Bundesliga and German Cup titles.
However head coach Jupp Heynckes, 72, who oversaw the treble five years ago, insists Bayern must do better if they want all three titles again.
“Any talk like that is the job of journalists – the Champions League is a different competition and we must improve,” said Heynckes.
“Everyone in the stadium saw that we found it hard in the first half.
“We didn’t find our rhythm and we were nervous – I don’t know my team like that.
“In the first half there wasn’t any tempo to our game, our passing was off and it allowed Besiktas to attack us more.
“The opener before the break gave us a psychological advantage and in the second half we saw a different Bayern team.
“We scored some great goals and played some good football.”
