According to Italian website Sportsenators.it, discussions between casual wear manufacturer Uniqlo and Federer "could be well advanced, even concluded", with the Japanese brand apparently prepared to pay Federer US$30 million over the next ten years, even after the 36-year-old has stopped playing.
"For three months I hardly saw any, I also didn't watch much TV or much tennis on the TV, because, as I didn't play it at all, there was not really goal for me to watch it and I am busy anyway as it is with my children, with training", said Federer. His previous deal expired on March 1, and he can now boost his annual income by nearly 30 percent. In the 2016 and 2017 editions, he lost to eventual Serbia's Novak Djokovic and Nadal.
Roger Federer missed the French Open and will now be entering ATP Stuttgart fresh after a long rest.
Federer, who arrived at Stuttgart for the Mercedes Cup at the start of the week, confirmed his deal with Nike had concluded but rubbished reports suggesting he already signed up with Uniqlo.
Despite the speculation, he arrived to the Stuttgart Open wearing a Nike T-shirt, shorts, trainers and a headband.
Only Rafael Nadal truly knows what he saw reflected when he glanced into the belly of the big silver bowl, but as he pressed his 11th French Open championship trophy against his cheek, his face began to crumple. Federer has no weaknesses and that is what makes him so hard to play against.
The Spaniard secured an 11th title at Roland Garros on Sunday and 17th major of his career.
Djokovic left the partnership to join Lacoste a year ago.
Despite this, Nadal has insisted he is not actively pursuing his grand slam rival.
The muscular Spaniard had won all 10 of his previous Roland Garros finals and although Thiem was the only man to have beaten him on clay over the past two seasons, the Austrian never threatened the claycourt master.
"If you told seven or eight years ago that I will be here at 32 years old having this trophy with me again, I will tell you that is something nearly impossible, but here we are".
"You have to be humble and accept that you have to work to improve things", added Nadal.
"It's not always that easy, especially on grass", Federer said on his return. You can't be frustrated if somebody have more money than you, if somebody have a bigger house than you, if somebody have more Grand Slams than you.
Thiem did at least remind Nadal of his age, saying; "I can still remember being 11 when (Nadal) won here for the first time and I watched on the TV".
