Unlikely but not impossible. There is a case to put to him. 1) Finish your career with a couple of Bundesliga trophies or come to United and end your career being a cult hero at Tottenham, Bayern and United. Being a United hero will do wonders for his post football C.V. More than Bayern and Tottenham except in Germany. It will open doors and give him a much bigger spotlight if he want to move to presenting or sponsorship or anything else.
2) Come get your leading Premiership top scorer accolade. Only 43 goals off. 15 goals a season for 3 years. This must surely be something he thinks about. Being known as all time Prem Top scorer (until Haaland comes. But we wont tell hm that) is a massive badge of honor. Any best striker in Prem discussions he will be there. He will be there anyway but not with the same zeal as being a Man Utd player and top Prem goal scorer of all time.
3) You have never won anything in England. This must stick in his craw. Nothing. Nada. It will always be a stick to beat him with and he must have always dreamed of winning something. Come to United and hopefully we get the Prem but even if not you could get an FA cup at least, heck a League Cup. Win something. Heck it could be argued that winning a League Cup could be more special than a fourth Bundesliga - for him.
I ask you Kane 'Have you reached all your dreams in the Prem. Are you satisfied. Will you look back and always wonder what could have been even with 4 Bundesliga titles.'
