The two great hopes for the future of men’s tennis slumped in the first round of Wimbledon, and both Alexander Zverev and Stefanos Tsitsipas admitted they are not yet up to it mentally when it comes to the Grand Slams.
Zverev has had enough success on the tour to reach No 5 in the world but he is yet to make a major semi final.
Asked whether his issue in five-set tennis was mental or physical, Zverev referenced unspecified personal problems.

Hopes for the future Alexander Zverev and Stefanos Tsitsipas both lost in the first round
‘Physically I'm fine. I can play 10 sets, no problem,’ said the 22-year-old German after a 4-6, 6-3, 6-2, 7-5 defeat to qualifier and world No 124 Jiri Vesely on Court 1. ‘Yeah, (it is) mental, I get down on myself a lot.
‘Life is also one thing. The last two days are very rough for me personally. I'm not going to get into details, but I have to fix that to play well on the court.’
He continued: ‘It was kind of a typical Grand Slam match for me. I started off well, then one or two things don't go my way, and everything kind of falls apart.
‘I didn't lose this match on tennis. It's just my confidence is below zero right now.’
Tsitsipas looked on the verge of tears after losing 6-4, 3-6, 6-4, 6-7, 6-3 to in-form Thomas Fabbiano of Italy, a player he thrashed here last year.
