Novak Djokovic says he doubted he would ever win another Grand Slam before ending a two-year drought by claiming his fourth Wimbledon title.
Djokovic, 31, won his 13th major by beating South African eighth seed Kevin Anderson in straight sets on Sunday.
The Serb struggled for form and fitness after his 2016 French Open win, falling out of the top 20 earlier this year.
“There were several moments where I was frustrated and questioning if I’d get back to the desired level,” he said.
“But that makes this whole journey even more special for me.
“I’m really grateful to go through these mixed emotions and turbulence mentally. I’m human and we all have to go through that.”
