"It is the worst feeling being so far in front. You just think, 'What if I do this? What if I do that?'," Daley told reporters.
"I try not to think about anybody else. It is a very individual sport. You can only think once you have finished.
"It has been a very, very long season. I am going to have a rest now. I have not had a day off in four weeks so I cannot wait for a lie-in tomorrow morning," added Daley.
