Former world number one Roger Federer, currently ranked number three in the ATP rankings behind his rivals Novak Djokovic and Andy Murray, is currently competing in his second grass court tournament of the season as the three-time defending champion at the Gerry Weber Open in Halle.

The Swiss maestro has a semifinal clash with German Alexander Zverev, a member of the Next Gen, young and upcoming tennis stars of the future for a spot in his first final of 2016. 

Federer a Firm Believer in the Swiss' Chances

Federer spoke with CNN about his homeland of Switzerland's chances of winning UEFA Euro 2016 in France.

"If you move on the group stage, you can really believe everything is possible." The former seven-time Wimbledon champion also added, "I play almost every tournament every single week, they play only sometimes and anything is possible on any given day especially in soccer with the power of the referee has, red cards, penalties and so forth."

Federer will be following Switzerland's progression through the tournament closely whilst he has tennis matches to play, "I wish the team the best and I will follow it very closely."

When Federer was playing in the Mercedes Cup last week in Stuttgart before his semifinal loss to eventual champion Dominic Thiem, he asked the tournament organisers if he could play his match at midday because Switzerland kicked off against Romania at 3pm local time in France.

On his official Twitter page during Switzerland's match with Romania, Federer tweeted "Thinking of biting my nails here, nervous for the boys." 

Federer will have time to watch his beloved Switzerland's matches next week, should they progress from Group A and he has a week off after this tournament concludes before his quest for his record eighth Wimbledon title begins later this month.
