Livetennis.com believes it's going to be quite difficult for that to happen given all that has transpired over the last few months.
Djokovic is undoubtedly in the prime of his form as the world no. 1 has now won six of the seven Grand Slams that he has last played in. Having capped the elusive French Open in May after defeating Andy Murray in the final, the Serbian has completed the Career Grand Slam as he now sets his sight to bigger records.
To put things in perspective, Djokovic's track record this season is 44-3, where two of those surprising defeats came in early rounds of ATP Dubai and Monte Carlo Masters. As for the last one, it came against Murray in the final of Italian Open.
Roaring with such a tremendous amount of momentum and showing absolutely no signs of slowing down, it is hard to imagine anyone else coming in and stopping the Serb from conquering the Wimbledon crown for the third consecutive time. Nonetheless, there are some players who are capable of going head to head with him and quite possibly, even going the distance.
Roger Federer is certainly the first name which comes into the picture. Hailed as the 'King of Grass', the world no. 3 has won the tournament seven times so far, while emerging as the runner-up since 2014. Needless to mention, it was Djokovic to whom he succumbed on both those occasions. However, Federer is capable of winning against the Serb in smaller occasions such as ATP Dubai and Cincinnati Masters as he showed last season, but it is the big stage where he stumbles. The head to head record is currently being lead by Djokovic by a slim margin of 23-22.
Despite the fact that he has incurred a couple of defeats in the build up to Wimbledon, he still looks confident. The Swiss maestro has certainly shaken off the injury problems from earlier this season, and is now on the rebound course. The two players are likely to meet in the semifinal, considering that they will be placed in the same half.
Andy Murray is another player in the list who is capable of defeating the world no. 1. Although he is well behind by 14 wins to catch up with Djokovic in the head to head tally, he is the only one after Federer to be able to trouble him. The duo have met in four finals this season already, with their rivalry getting more intense by every match they play.
At the number 2 spot, Murray has had a good season so far, but will be eager to add another Wimbledon trophy to his collection. The two players are likely to meet in the final, and we may get to witness the 2013 feat, where the Brit won against Djokovic to lift his first Wimbledon trophy.
Rafael Nadal too is certainly in the list as well, but the Spaniard himself has had a rather quiet season so far. His rivalry with Djokovic is fierce, as lags 26-23 in the head to head tally. However, it is quite unlikely for him to defeat the Serb, considering that he last won against him in 2014 Roland Garros, and has lost in all their matches since then.
If Djokovic doesn't suffer from any eleventh hour fitness concerns, he looks to be in line to make it five in a row.
