Seven-time Wimbledon champion Roger Federer has described Novak Djokovic's form over the last four years as "utterly dominant".
The pair will meet later today in the Wimbledon final for the second successive year, and ahead of the contest, the Swiss has hailed his opponent's consistency.
He told reporters: "It's great to play Novak anywhere these days because he's a great player. He's had great success, unbelievable success actually, throughout his career but especially the last few years, he's been unbelievably dominant.
"I'm just happy personally for myself to be back in a final. That it's against Novak, the world number one, it obviously adds something extra."
Federer has beaten Djokovic in 20 of their 39 matches.
