Barcelona forward Kevin Prince-Boateng has represented a host of big clubs in his career, including Tottenham, Borussia Dortmund, Milan, Schalke, and Eintracht Frankfurt, but he has not completed a second season at the same side since 2015.

Boateng believes he could have played for Manchester United or Real Madrid for a decade had he been more motivated. Boateng said, “I know very well that I have also failed with my motivation, which has not always been 100 percent there.”

The Ghanaian attacker has made three appearances for the Catalans since moving to the Camp Nou on loan from Sassuolo in January.

The 32-year-old who is now coming towards the end of his career believes his mentality was not strong enough as a young player, “Mentality is crucial. I started too late to really think about [my career].

As an 18-year-old, I had to fix everything myself, I would have needed an agent or a family to push me in the right direction.”

“If I would have had the absolute will, I would have been a starting XI player at Barcelona or would have played 10 years for Real Madrid or Manchester United.”

Barcelona, who wrapped up the La Liga title at the weekend, have the option to sign Boateng on a permanent basis for £7m this summer. “
