Federer issues stern warning to Nadal ahead of Stuttgart return
Stuttgart: The Swiss star says his "expectations are high" as he gears up for the grass-court season — which kicks off in Stuttgart on June 11.
Federer is currently enjoying a two-month break while arch-rival Rafael Nadal dominates on clay. The Spaniard has won the Monte Carlo Masters and Barcelona Open as he prepares to defend his French Open title.
Federer and Nadal will be the heavy favourites to win the summer Grand Slam at Wimbledon - but it is the world No. 2 who is out to defend his crown, which he is desperate to retain.
"Of course, my expectations are high on grass, and I'm looking forward to playing again in Stuttgart this year," Federer said.
"The atmosphere at the TC Weissenhof is wonderful. "You can immediately feel that there is much life in the club. The tournament is very well organised and spectators are there in the matches." Federer last year outlined further reasons why he likes to compete in Germany.
"It's not far away from home," he added.
"And of course, it was funny to drive once again in Germany on highways."
The Swiss star started 2018 in top form as he won the Australian Open to take his career Grand Slam tally up to 20.
Success at the Rotterdam Open and an Indian Wells final appearance swiftly followed before a shock defeat to Thanasi Kokkinakis at the Miami Open caused him to hand the world No. 1 crown over to Rafael Nadal.
