Manchester United midfielder Mata was the first player to commit to the cause, but he has now been joined by Bayern Munich’s World Cup-winner Hummels.

The Spain international has revealed that he was contacted by Hummels, who is also hoping to use football to make a difference around the world.

“I feel we could be doing more to connect the increasing revenues in football to some kind of deeper purpose,” the Germany defender said in a press release on the Common Goal website. “This is what struck me about Common Goal.”

Mata added: “I don’t actually know Mats personally, so I was pleasantly surprised when he contacted me to talk Common Goal.

“He really gets what we’re trying to achieve and is the perfect team-mate to have on board at this early stage.

“The fact that a World Cup holder - at the peak of his career with one of the biggest clubs on the planet - has chosen to make the pledge shows the power and magic of what we’re doing.”
