Former Bayern Munich coach Jupp Heynckes is shocked by the state of the transfer market.

Paul Pogba left Juventus for Manchester United in a €100 million world record transfer over the summer.

Heynckes believes football has "gone off the rails" following the latest transfer window.

Heynckes retired after leading Bayern to a Bundesliga, DFB-Pokal and Champions League treble in 2013 and he is glad he no longer has anything to do with a game which he says has transformed into a business.

"Just look at this inflamed transfer window," Heynckes told Die Welt newspaper. "Football has gone off the rails. It's lost its spirit. Football is business. It's all about being quick, quick, quick - nobody has any patience nowadays."
