Roger Federer: F1 legend Kimi Raikkonen issues challenge to Swiss star
While the Finnish star has been preparing for the 2018 F1 season, Federer has been busy returning to the top of the world tennis rankings.
The 36-year-old won the Australian Open in January before regaining his world No 1 spot in Rotterdam last month.
But as Federer prepares for the Indian Wells Masters next week, he may have a new practice opponent.
Despite the F1 season getting underway in Australia later this month, Raikkonen has challenged the Swiss star to a match on the tennis court.

The duo have a good relationship, and Federer often keeps up to date with motor racing by attending the Swiss Grand Prix.
The tennis legend was also spending time with other senior sporting figures at the 2018 Laureus Sports Awards last week.
Federer won Comeback of the Year and Sportsman of the Year in Monaco.
Martina Navratilova awarded her fellow tennis star the accolade and heaped praise on his ability and fighting spirit.
