Roger Federer’s win over Robin Haase in the quarter-final of the Rotterdam Open this weekend saw him become the oldest world No 1 on route to the final.
The Swiss star defeated Grigor Dimitrov 6-2 6-2 yesterday afternoon to pick up the 97th title of his career.
But the defining moment of Federer’s week was the victory over Haase as he dethroned Rafael Nadal to go back on top for the first time in over five years.
And his long-term coach Severin Luthi, who has been touring with him since 2007, was in the crowd to watch the match.
Federer arrived in the Netherlands with his other coach, Ivan Ljubicic, but Luthi was not present.
However, Luthi did make the trip for the all-important game and admitted he did not want the 36-year-old to know he was in the crowd.
“Actually Roger has no problems in such situations,” he told Swiss newspaper Blick.
“But this was special anyway. I thought, I say clever not that I come. I followed such a feeling.
“So my wife Claudia and I were sitting in the crowd somewhere for the quarterfinals, hoping that nobody would notice.”
Asked if Federer knew he was coming, he added: “I think no – unless he acts as if he did not know anything.
“Anyway, I said to the people of the tournament, they should not reveal anything, do not put me in the first row.
“Otherwise, any TV camera will catch me or Roger will see me.
“I’t’s a special moment, I just had to be there for it – for me and for him. Also many friends said I should be with Roger.
“I really hoped Roger would win, then at least he can celebrate a bit with some friends.
“But even if he had lost, he might have been glad that someone is there and a little less disappointed.”
