Roger Federer

The defending champion and obvious favourite for the 2018 Wimbledon title.

He skipped the entire clay season, just like he did last year, and has already won the Mercedes Cup title in Stuttgart beating Nick Kyrgios and Milos Raonic along the way, and was the runner-up at the Gerry Weber Open in Halle.

People were shocked that he lost to Borna Coric in the final in Halle, a title he has won nine times in the lead up to Wimbledon, but after not playing tennis for almost three months and then playing nine matches in two weeks, there is every chance he was just a bit worn-out by the end of the second week.

Sometimes we forget that he is almost 37 years old.

Federer has won the most Wimbledon titles of any man in the open era with a total of eight wins with the first being in 2003.

He is the G.O.A.T of tennis but especially on grass and he always brings his absolute best to Wimbledon so he is by far the one to beat.

Rafael Nadal

Rafael Nadal is coming off an incredible clay season, as per usual, but he has played no matches on grass in the lead up to Wimbledon.

It is no secret that grass is the current world number one's weakest surface but he has won Wimbledon twice nonetheless.

Since he made the final in 2011, Nadal hasn't made it past the fourth round which isn't a great sign but he is a champion and you can never write him off.

Novak Djokovic

He is a three-time champion at Wimbledon but Novak Djokovic has been battling a serious elbow injury since he pulled out in last year's quarter-finals.

He took the rest of 2017 off after Wimbledon last year and returned to tennis at this year's Australian Open where he made the quarter-finals but was still suffering from the elbow injury.

The former world number one had surgery on the elbow earlier in the year and has had some good results since being back on the tour but he is still far from his best.

He hasn't won a title for 12 months or a five-set match since last year's French Open so if he gets pushed to a fifth set at Wimbledon, he will be in trouble.

Andy Murray

The fourth member of the ‘big four' will need to produce something special to win Wimbledon this year.

Andy Murray has taken a year off from tennis since Wimbledon last year after a nasty hip injury.

He tried to return in Australia at the start of the year, but he was still suffering pain and opted to have surgery with the aim to be back for the 2018 grass season.

The former Wimbledon champion lost his first match back against Nick Kyrgios in three sets at Queens and lost his second round match against compatriot Kyle Edmond at Eastbourne.

Murray will go into this year's Championships very underdone without any best of five tennis under his belt, but it will be good to see him back out on his home court after many feared he wouldn't be able to play tennis again.

Marin Cilic

Marin Cilic has been in great form in 2018, pushing Roger Federer to five sets in the Australian Open final and winning Queens, the best Wimbledon warm-up event.

The fast-paced surface of grass suits his big serve and forehand and he was the runner-up  to Federer last year.

Seeded at three, Cilic could be the biggest danger to Federer's title defence.

Grigor Dimitrov

The Bulgarian has been touted as the ‘mini-Fed' since early on is his career but he is still yet to reach the heights that people expect he will.

He is the reigning ATP World Tour Finals winner and he made the semi-finals at Wimbledon in 2014 but his best result at the tournament since then has been last year when he lost to Federer in the fourth round.

He featured at the Queens tournament but lost in the second round in straight sets to Novak Djokovic.

Seeded at six, if he gets the right draw and brings his best game, he could make it very deep into Wimbledon this year.

Milos Raonic

Milos Raonic made the final at Wimbledon two years ago and lost to Roger Federer in the quarterfinals last year.

The big serving Canadian has a game that is hard to stop on grass with an explosive serve that can consistently be fired down at 230km/h, a big forehand and a net game that he has spent years improving on.

Raonic made the final at the Mercedes Cup in Stuttgart, losing to Federer and had to withdraw from Queens in the second round due to a strain in his right pectoral muscle that occurred at the end of his first round match.

It appears that the withdrawal from Queens was mostly just precautionary to ensure he didn't cause further harm to hinder his Wimbledon campaign.

The 13th seed has been struggling with injury over the last couple of years and hasn't been able to get much continuity in his game but coming out of Stuttgart, he said he was finally fit again and as long as the pectoral injury isn't serious, he is a major threat at Wimbledon this year.

Nick Kyrgios

Seeded at 16, Nick Kyrgios isn't just Australia's best chance at Wimbledon this year, but he is a serious contender to go deep into the tournament.

He played two lead up tournaments on grass and he lost to the eventual title winner in both.

He pushed Roger Federer to three sets, two of which went to tight tiebreaks in Stuttgart, and lost to Marin Cilic in two tiebreaks at Queens.

The Aussie hothead has battled an elbow injury for the most part of this year and took the advice of health experts to have two months off to make sure it was 100 percent healed and ready to go for the grass season.

Kyrgios has always said that Wimbledon is his favourite tournament and one that he is hungry to win and if he can keep his head straight and his body fit, there is no reason why he can't go all the way this year.
