Roger Federer holding his trophy at the Dubai Championships.

Roger Federer’s enduring class shone through again as the Swiss maestro beat world number one Novak Djokovic 6-3 7-5 to win the Dubai Championships for a seventh time yesterday.

The 33-year-old’s serve is the least praised of his repertoire but it was his awesome delivery that blunted Djokovic’s baseline game, taking his career ace haul past the 9,000 barrier with 12 more, several at vital moments.

Federer went into the match with a 19-17 winning record against Djokovic, although the Serb beat him in last year’s gripping Wimbledon final.

The match proved to be a tale of chances taken and chances missed – Federer converting his two break points with clinical efficiency, while Djokovic failed on all seven of his.

“We get the best out of each other,” Federer said in a courtside interview after winning an 84th tour singles crown.

“I’m pleased I did some good serving when I had to. I definitely won the big points tonight.”

The first set’s decisive moment came with Djokovic serving at 3-4. Federer advanced to blast a forehand down the line for the Swiss’s first break point, which he converted when Djokovic clubbed a forehand long.

That put Federer 5-3 up and he served out to clinch the set.

In the second, both players became more comfortable on serve, the score racing to 3-3 without a single deuce.

Serving at 3-4 and 15-40 down, Federer despatched two aces and two service winners to hold.

The Swiss repeated the trick again, serving at 15-40 and 4-5 down, he made another two aces and a service winner to save two set points and square the set.

A cross-court winner gave Federer a break and 6-5 lead and although he fluffed his first match point on serve, he set up another with a second serve ace that he converted with a powerful forehand off a weak Djokovic return.
