It is always rather tricky trying to pin down the exact reasons for a champion's slump.

Roger Federer has, by his lofty standards, had a terrible 2008 and is not looking particularly happy with his game. Diagnosed with mononucleosis after falling to Novak Djokovic at the Australian Open, Federer has lost a further three matches.

Andy Murray in Dubai was not as huge a shock as the media would have us believe. Murray is very talented and can outplay any of the big names on his day. His attitude and inconsistency is what prevents him from bettering himself.

'Anyone who thinks that Federer will not be primarily attempting to relinquish the French title from Nadal, or that the Spaniard won't be fighting tooth and nail to retain it, needs their head examined'


Indeed, it was not until Mardy Fish whipped Federer in straight sets at Indian Wells that people noticed there was no evident fight or fire coming from the Swiss genius. That was very uncharacteristic of the world number one and extremely worrying for his army of followers.

Federer has been at the pinnacle of the world rankings for 219 consecutive weeks and he is, of course, human - everyone runs out of steam at some point. The aura that surrounds Federer and his achievements merits a case for caution on premature shouts about his slippery slope from the top of the Tennis world.

Although recently defeated for a fourth time this year - by Andy Roddick in the quarter-finals of the Sony Ericsson Open in Miami - Federer displayed some very encouraging signs of recovery. In a three-set loss, he was ahead on forehand, backhand and volley winners against the rejuvenated American.

Encouraging? Or ominous for the rest of the players only too willing to take Federer's throne? I would tend to agree with the latter. In the run-up towards the French Open, perhaps Federer is finally shaking off his illness and hitting the ground running in his quest for that elusive clay court title.

One man who will enter the clay court season in a slightly more boisterous mood is the king of clay, Rafael Nadal. He's 21-6 for the season in the win-loss column and a runners-up prize in Miami against Nikolay Davydenko sees the young Spaniard in a good position.

Although comprehensively beaten by the Russian, an ever-positive Nadal remained upbeat, saying: "This tournament is going to give me, I think, positive feelings for the clay season."

Nadal seems extremely relaxed and fresh, as he should moving into his favourite part of the calender. Neither Nadal nor Federer have hit the heights so far this year, yet rumblings throughout the tennis world are rife predicting that the two most consistent and best players on the planet are about to crumble.

Only three months or so into the season with three Grand Slam events to come shows a lack of foresight on the part of many doubters. For 140 weeks Nadal has been attempting to topple Federer from the top spot and if Djokovic, Davydenko and Roddick think that the young Spaniard - or Federer for that matter - will simply fade away, they are being very naive.

These two men have set the standard over the last few years and are not even close to chucking in the towel yet. Rankings do not lie and anyone who thinks that Federer will not be primarily attempting to relinquish the French title from Nadal, or that the Spaniard won't be fighting tooth and nail to retain it needs their head examined.

No one can forsee injuries or lack of form, but both men are slowly building up the right momentum and form at just the right time.

Nadal and Federer know each other very well and, strangely for the top two in tennis, hold each other in high regard both on and off the court. It would be foolish for anyone to think that the two of them will not still be sitting at the top of the tree come the end of the season.
