Heynckes - the brains behind Bayern's 2012/13 unprecedented Bundesliga, DFB Cup and UEFA Champions League haul - has worked wonders since returning to the hot seat in place of Carlo Ancelotti on 6 October. The 72-year-old has successfully turned a six-point deficit into a six-point lead at the top of the Bundesliga standings and secured the Bavarian giants' safe passage into the DFB Cup third round and Champions League last 16.
"We can definitely win the Bundesliga, DFB Cup and Champions League," Lewandowski said in an interview with Playboy. "It's not that long ago since Jupp Heynckes took charge, but when I think about how he works with us in training, I think we can achieve a lot."

The Poland international, who has scored 52 goals in all competitions in 2017 alone, also mooted a possible switch to motorsport when the time comes for him to hang up his playing boots.
"Driving is my escape and I've always been very interested in motorsport," the 29-year-old revealed. "The problem is that you have to commit 100 per cent to the sport, and that comes with its own sacrifices. I've spoken to my wife about it, but we'll have to see."
