The Black Stars captain subsequently joined Al Ain in the Arabian Gulf League to the surprise of many.

However, Gyan has now revealed that the high tax demands on footballers in England forced him to leave the Stadium of Light.

"[The tax demand on players in Europe] is too much. In England they take like close to 50% [of your salary as tax]. A player trains everyday then at the end of the month you cut his salary by 50%. I don't think it's good," Gyan opined in an interview with Joy Fm.

"Let me reveal this secret; I will say that [high taxes] was one the reasons why I left Sunderland. That was one of the factors. In China they tax too, but there the clubs pay the tax and they give the player a net salary.

"But in England the team doesn't pay, it is the player that has to pay the tax. So it you are earning $100,000 a month, then it's virtually $50,000. But in China if you are earning $100,000, your team pays your taxes and you take home $100,000."

Gyan currently plays for Al Ahli Dubai, where he is on loan from Chinese Super League outfit Shanghai SIPG.
