RAFAEL NADAL vowed to take the fight to Novak Djokovic and warned the new world number one not to expect his golden spell to last forever.

Djokovic took his rightful place at the head of men’s tennis this morning after yesterday defeating Nadal 6-4 6-1 1-6 6-3 to clinch his first Wimbledon title.

It capped a dream seven months for the Serb which began with a first Davis Cup triumph last December and also included the Australian Open and four Masters Series titles.

Djokovic has won 50 of his last 51 matches, losing only to Roger Federer in the semi-finals of the French Open, and Sunday’s victory was his fifth of the season against Nadal.

The Spaniard knows exactly how his rival is feeling after his stunning year in 2010, where he won three successive grand slams, completing his set with a US Open final triumph over Djokovic last September.

Nadal said: “He’s in the best moment of his career.

“I am in one of the best moments of my career. But still not enough for him. I have to play longer. I have to play more aggressive. I have to have less mistakes. Yes, that’s what I have to do. My experience says this level is not forever. Even for me, when I was last year winning three grand slams, my level of last year is not forever. Probably the level of Novak is not forever.”
