'Something is going wrong, it is very frustrating'
"There are always multiple factors in match like this, but it didn't go well on the set points. I didn't break him at the Hopman Cup either, so something is going wrong. It is very frustrating."

I'm the happiest man on earth right now, says Tsitsipas
The veteran Swiss maestro has failed to reach the last eight in Melbourne for only the second time in 16 years.
It was one of the biggest shocks of the tourney this year.
The 20-year-old Tsitsipas saved all 12 break points of Federer and ended up earning a special victory.
"I'm the happiest man on earth right now, I can't describe it," Tsitsipas said.
Federer will rue missed opportunities
Tsitsipas will face Spain's Roberto Bautista Agut in the quarters, who beat Marin Cilic
He had played against Federer earlier in the Hopman Cup last month, where Federer nicked a tight two-set win.
Federer will look back into the game and rue the missed chances.
His aim of winning a record seventh men's singles title ended on a rather sour note.
I lost to a better player: Federer
.@rogerfederer: "I lost to a better player who was playing very well tonight. Hung in there, gave himself chances at some point, stayed calm. It's not always easy, especially for younger guys. Credit to him for taking care of that."#AusOpen pic.twitter.com/F60r32OdnX— #AusOpen (@AustralianOpen) January 20, 2019
