The Beatles once sang of a long and winding road and it's what awaits Jose Mourinho and his charges if they are going to make the Portuguese's return to Stamford Bridge a successful one next season.
A Premier League campaign is one of twists and turns, where the pendulum often swings. In one month you can be flying high, en route to glory only for it to slip through your fingers, while a run of victories can turn an otherwise bad year into a positive one.
Indeed, Chelsea have experienced both sides of the coin after leading the way last term before a home defeat to Manchester United in October saw their season begin to unravel before doing just enough to finish third in the table.
The Blues will face a new-look United a little earlier this term, with their first clash of the season coming on just the second weekend of the new campaign.
That fixture will give us some early drama no doubt, but in terms of helping decide where the title will ultimately reside come May, with some 36 games to follow, it will not be as vital as some we have seen in previous years.
But what are the games that will impact Chelsea's title challenge? Bleacher Report takes a look at six that will play their part.
