Novak Djokovic does not believe his route to what would be a maiden Wimbledon final has been made easier by Jo-Wilfried Tsonga's stunning come-from-behind win over Roger Federer.
When Serbian second seed Djokovic walked off Court One with a 6-2, 3-6, 6-3, 7-5 quarter-final win over Bernard Tomic under his belt, he would have expected to find it was Federer - the only man to have beaten him in 2011 - waiting for him in the last four.
Federer had taken a 2-0 lead, something he had not surrendered in 178 grand slam matches, but dramatically capitulated on Centre Court, although Djokovic, who watched the end of that match on television, does not reckon his task has been made any easier as a result of the Swiss' demise.
"I really need to work in my game. I hope I can perform a little bit better than I did," he said.
"That's what matters for me the most, regardless of who is across the net.
"Tsonga came back from 0-2. It's an amazing comeback. He's been playing great in the grass-court season.
"He played really well at Queen's (getting to the final) and he's been winning against top players. He's very dangerous."
Djokovic added: "Grass courts are not my favourite surface but I know I can play well on them," he added.
"It's different circumstances. It's a grand slam. I will definitely try to get ready and play well on Friday.
"I can play a lot better than I did. I've been up and down but now it's going to go up."
