With the top six running away from the rest of the Premier League and all still in contention for the title, Telegraph Sport assesses their various strengths and weaknesses.

1. Chelsea (P20, Pts 49)

Main strengths

Deservedly odds-on favourites to lift the Premier League trophy in May, there are all manner of signs to suggest Chelsea will put their defeat at White Hart Lane behind them and maintain their grip at the top of the table. A seven-point margin over all but one team is a healthy advantage at this stage of the season, while a number of their players know what it takes to win the Premier League after doing so in 2014-15. Antonio Conte has rejuvenated the squad this season, they can score, they can defend and they are most certainly still the team to beat.

Main weaknesses

There are few immediate weaknesses in the starting XI Conte has been fortunate enough to field week-in week-out this season but, as Arsenal and Spurs have shown, they are not unbeatable up against a team at the top of their game. Conte's faith in 3-4-3 could be tested should one if his wing-backs suffer injury, while the Italian has yet to show faith in Michy Batshuayi if Diego Costa comes a cropper. They have also won a large number of their games by just one goal.
