Chelsea's Premier League title chase this season has been a surprising one, but with just 11 games to go until the end of the campaign, the Blues are largely considered the clear favourites to secure the trophy in May.

After all, Antonio Conte has led his side 10 points clear at the top of the table - and with the teams below them struggling for form, it seems unlikely they'll be caught before the end of the season.

However, Chelsea struggled last season and a return to that poor form could be just around the corner. So considering the wealth of top quality teams that the Blues still have to face, it will not be an easy ride for Conte.

Indeed, there are a number of fixtures that could very well define Chelsea's season, and likewise, they could yet cost the Blues the Premier League title.

With that said, here are 3 games that could still cost Chelsea the title this season...

Manchester City

Manchester City's form this season has been up and down, but on their day they can beat anyone.

Indeed, Chelsea won the first meeting between the pair fairly easily - with goals from Eden Hazard, Willian and Diego Costa sealing the points for the Blues on that occasion.

However, considering the Citizens lost out in the Champions League to Monaco, all hands will certainly be on deck to ensure Guardiola's side finish the season strongly. A top four finish is absolutely vital, and so they will need to put in a big performance against Chelsea.

Conte had an easy ride last time, but that could change this time around - and the Italian must be aware of the offensive threat that the Sky Blues bring.

Manchester United

Likewise, Chelsea have done well against Manchester United this season, with a recent 1-0 victory in the FA Cup ensuring progression to the semi-final of the competition.

Jose Mourinho, then, will be desperate for revenge, and you can bet that he will be going all out to finally get a win over his old side.

Chelsea may get lucky in that the Europa League is taking precedence for Manchester United over the Premier League at present, but this game will not be an easy one.

The game is Chelsea's last fixture against one of the Premier League's biggest sides, and so it will be a significant hurdle for Conte to jump over.

Middlesbrough

Whilst on the surface Chelsea will be favourites going into this game, Conte must be well aware of the threat that Middlesbrough might bring.

With their manager Aitor Karanka recently being sacked, you can expect the players to pick up steam and attempt to turn their season around as the campaign progresses, and that could pose a problem for Chelsea.

Likewise, with this game the third last in Boro's calendar, it could be a decisive fixture as they look to halt the threat of relegation.

Chelsea must not be complacent, as this game could be vital for both sides.
