While Chelsea and Manchester United may not be the two title favourites this season - like they have been in the past - there is certainly no doubt they still have world-class talent in their respective squads.
Both clubs acquired world-class managers this summer in the form of Antonio Conte and Jose Mourinho and spent a combined £275 million in the past transfer window.
With the Blues three points behind Arsenal and Manchester City and United a further two points adrift, both sides know a win would be crucial in hauling themselves into the title mix.

So, here is a Chelsea and Manchester United combined XI based on this season’s stats.
Goalkeeper | David de Gea | WhoScored rating: 6.60
David de Gea hit the headlines with a couple of great saves against Liverpool and just edges out Thibaut Courtois. He’s conceded fewer goals and made more than twice as many saves as the Belgian.
Right-back | Antonio Valencia | WhoScored rating: 7.48
Many said right-back was a problem area for United this season but Antonio Valencia has impressed. He’s made more tackles than any of his teammates (23) and comfortable beats Branislav Ivanovic in this position.
Centre-back | Eric Bailly | WhoScored rating: 7.30
The 22-year-old arrived for £30 million this summer and looks to be a decent acquisition. He’s made a team-high 29 interceptions and completed 88.8% of his passes.
Centre-back | Daley Blind | WhoScored rating: 7.68
Daley Blind’s versatility has ensured he’s featured regularly for Mourinho’s side this season. The Dutchman has played at both centre-back and left-back and is currently averaging 2.7 tackles and 2.7 interceptions per match. He’s also registered two assists.
Left-back | Cesar Azpilicueta | WhoScored rating: 6.97
At last, a Chelsea player. The Spaniard is renowned for being solid and he’s exactly that. N’Golo Kante is the only player in the Chelsea squad to have played more passes than him with the full-back racking up 437.
Centre-midfield | Maurouane Fellaini | WhoScored rating: 7.47
Maurouane Fellaini used to be a scapegoat at Old Trafford but he’s proved his worth in this United line-up this season. He’s won 3.5 and 4.8 aerial duels per game and has successfully completed 89.9% of his passes.
Centre-midfield | Ander Herrera | WhoScored rating: 7.40
Ander Herrera is a cult hero at the club at the moment and it’s hardly surprising given his recent performances. He completed a season-high of 11 interceptions against Liverpool, while also making seven tackles and six dribbles at Anfield.
Right-wing | Willian | WhoScored rating: 7.67
The Brazilian could return to Chelsea’s starting line-up after being compassionate leave for the match against Leicester. Willian has started the season brilliantly, scoring twice and creating more chances per game (3.8) than any other Premier League player.
Attacking-midfield | Paul Pogba | WhoScored rating: 7.60
Paul Pogba may have received plenty of criticism for his performance since returning to Old Trafford but, according to the stats, the Frenchman is playing very well. He has made more passes per game (66.4) and dribbles (2.6) per game than anyone else in the team.
Left-wing | Eden Hazard | WhoScored rating: 7.59
Eden Hazard had a pretty disappointing campaign last season but the Belgian is firing this time around. He’s scored three league goals and has completed more dribbles per game (4.4) than any other Premier League player.
Striker | Diego Costa | WhoScored rating: 7.60
Diego Costa beats Zlatan Ibrahimovic in this line-up after two assists and a league-high seven goals. He’s scored two more than the Swede and has taken fewer shots per game (3 to 5.1).
