Bayern have all but secured their qualification to the Champions League quarter-finals ahead of travelling to Istanbul on Wednesday.
A brace apiece from Robert Lewandowski and Thomas Muller and one from Kingsley Coman leaves the Turkish outfit very much playing for pride in front of their own fans.
No team has ever turned a five-goal deficit in the Champions League, though four have overturned four-goal disadvantages, so Senol Gunes & Co. will be heading home.
Besiktas are without the suspended defender Domagoj Vida after his red card at the Allianz, but they will have an in-form Ricardo Quaresma to call upon.
The Portuguese winger has provided four assists in the competition so far and scored against Bayern in a knockout tie for Porto in 2014/15.
Last season’s Turkish SuperLig winners currently sit second in the domestic standings, having won all three of their top-flight assignments since losing so comprehensively in Munich. A much-changed side won 1-0 at relegation-threatened Genclerbirligi on Saturday.
