Premier League: Title, Champions League and relegation battles heat up as run-in begins

It's a bumper weekend of Premier League football on Sky Sports, with the run-in well under way.

The Premier League title race is on, with Man City revving up and injury-hit Arsenal stuttering.

And there's all to play for down at the bottom, as Tottenham hope Roberto De Zerbi can lead them away from a shock drop.

Here, we explain how this Sunday will shape the narrative through the Premier League as we reach the business end of the season...

The 7-0 thrashing of League One bottom club Port Vale in the FA Cup was a timely boost for Chelsea and Liam Rosenior, given the four-game losing streak they'd been on before the tie and the tumultuous international break which saw the club post a record loss and Enzo Fernandez and Marc Cucurella make unwanted headlines.

But the pressure and intensity comes right back on the Blues and their head coach this Sunday when a rejuvenated Man City come to the Bridge. Rosenior reckons his team have "come back stronger" after he figured out what needed fixing after their bad run before the international break. He will need to show he has the solutions this weekend.

If not, City - eager to build on their hammering of Liverpool in the Cup - have the capability to deal a big blow to Chelsea's top-five ambitions in the Premier League.
