Roger Federer is the star attraction at this week's Gerry Webber Open at Halle in Germany.
The 31-year-old top seed is yet to win an ATP Tour event this year, as he turns his attention to grass ahead of his title defence at this month's Wimbledon Championships.
Federer has won the Halle event five times but on his two most recent appearances has been beaten in the final - by Lleyton Hewitt in 2010 and Tommy Haas last year.
The world No 3 lost at the quarter-final stage at Roland Garros, sent packing in straight sets by Frenchman Jo-Wilfried Tsonga.
But Federer is unconcerned saying: "Halle is one of my favourite places on tour, and being successful here makes it even more likable.
"Paris has little to do with Halle or Wimbledon but, looking back, I am really disappointed with my match against Tsonga.
"I didn't really expect to necessarily win a lot of titles, and I thought I played well in Rome and Paris, until the match with Tsonga.
"I now feel that the best time for me is still to come in the second half of the year.
"It's a very important phase of the year, leading to Wimbledon and the North American swing.
"To win here (in Halle) would be a good build-up for Wimbledon".
Federer, whose most recent ATP title came on hard court in Cincinnati last August, was hoping to enjoy an extended run in this week's doubles event alongside partner Haas but the pair suffered a first round defeat losing 7-6 (7-3) 6-4 to Jurgen Melzer and Philipp Petzschner.
