The wait is finally over as Wimbledon gets under way this week, weather permitting, of course. It promises to be a pulsating tournament with King of Wimbledon, Federer, facing challenges to his crown from the new generation.

Nadal and Djokovic go into the tournament as number one and two seeds but after an impressive French Open, on possibly his weakest suface, Roger is the bookies favourite (23/10, Sportingbet). Rafa is hot on the heels of the six time champion, the world number one is a close second favourite (265/100, Sportingbet) to make it back-to-back titles.

Djokovic, beaten only once this season is 1 best priced 4/1 with WilliamHill, followed by the home favourite Andy Murray at 6/1 also with Sportingbet. Any of the four could win it, with the rest of the field seemingly out of contention; Del Potro is the 5th favourite at 66/1.

Despite it seemingly being a four-horse race, there is plenty of talent on show this year, here are some matches to look out for on Tuesday in the first round.

John Isner v Nicolas Mahut (Isner to win at 1/2 with Boylesports)

This match broke the record for the longest ever match at the tournament (and in tennis history), lasting over 11 hours when the two met last year. Isner finally won the final set, 70 games to 68 and the American almost caused an upset in the French Open against Nadal, taking the eventual champion to five sets.

His unstoppable serve make! s the 1/2 on offer from Boylesports worth taking for another victory against Mahut.

Kei Nishikori v Leyton Hewitt (Nishikori to win at 3/4 with Boylesports)

Nishikori is a self-confessed Hewitt fan after growing up watching the Australian triumph at Wimbledon back in 2002. The young Japanese player was only 12 at that time but now trumps Hewitt in the rankings by almost 100 places.

Former champion, Hewitt has struggled for form and dropped to number 130 and carrying a foot injury, should be no match for the 21 year old Nishikori.

At Eastbourne Nishikori made the semi finals, whilst Hewitt retired on Tuesday after limping off-court against Olivier Rochus and if it was any other tournament the injured foot would probably keep him out of the tournament, it will more than likely see him knocked out here, nonetheless.

James Ward v Michael Llodra (Ward to win at 2/1 with Blue Sq)

Ward caused huge upsets at Queens, first knocking out number 4 seed Stan Wawrinka then reigning champion Sam Querrey and Adrian Mannarino before a valiant effort against Tsonga saw the British number two lose out on a final place against Andy Murray.

Llodra has a good record on grass but the Frenchman is nursing a leg injury that forced him to retire at Queens against Tsonga. With the home crowd on his side and a confidence building performance on grass, Ward looks a good bet for another upset.

The Londoner has been training with a cage fighter to give him the winning mentality which showed in his fearless displays against some of the top players a few weeks ago, if he can repeat his wonderful serving he has a great chance of making this another memorable tournament.
