Roger Federer joined Novak Djokovic in the demand for higher prize money at the Grand Slams, as the 19-time Grand Slam champion's participation now adds weight to the debate. The Swiss ace stated that his fellow players also had an agreement with the Grand Slam pool, which has run its course.

The 2017 season has given the Grand Slam Board a lot to ponder upon and they have released a list of changes after their meeting, in London, that could be enforced in 2018. A major change would be the players being penalized if they decide to withdraw just before a tournament or in the first round.

Roger Federer has always featured in the list of the world's highest paid tennis players and between June 2016 and 2017 made a cool $64 million. Federer has a lot of sponsors by his side as well and he charges $2 million to play exhibitions and over $1 million to play ATP 250 and 500 events.
