Rafael Nadal's recent victory in the Rogers Cup proves he appears to be over his injury troubles again but his claim he can be world number one by the end of the year looks far-fetched.
Nadal was plagued by serious knee problems throughout much of 2012 but appeared to have recovered when he justified the tennis betting odds and won the French Open in fairly convincing style earlier this year.
However, he was then surprisingly knocked out in the first round at SW19 by Steve Darcis and fresh questions over his fitness were rightly raised.
The Spaniard did not look to be in good shape in London, but he has bounced back well since and took just over an hour in the Montreal final recently to crush home favourite, Milos Raonic, 6-2 6-2 to claim his eighth title and fourth Masters 1000 win of the year.
Now he says he has set his sights on overhauling current world number one Novak Djokovic – who he also beat on the way to Rogers Cup glory – as he believes he is close to rediscovering his very best form, even if he knows it will be a tough task.
“I feel I have an advantage, but not enough to say that I am the favourite,” he said. “We have to realise how many points I have to win to be number one. I think I will not be number one if I have less than 10,000 points at the end of the season. Today I have 8,000. I need to win minimum 2,000 more.
“That's very difficult in this part of the season, but I'm going to try.”
So, despite his optimism, there remains plenty of doubts among fans who bet on tennis about his overall fitness and, as we have seen over the past six months, winning one title does not necessarily mean others will quickly follow.
Nadal must also contend with the ever-improving Andy Murray who, fresh from his deserved Wimbledon triumph, will be desperate to also usurp Djokovic at the top of the rankings.
You wouldn't expect anything else but a positive outlook from Nadal but it looks unlikely he will fulfil his ambition of returning to world number one again by the end of year.
