Chelsea picked up their seventh successive Premier League victory on Saturday courtesy of a 2-1 success over previously unbeaten Tottenham at Stamford Bridge

The Blues were comfortably second best for most of the first half though, and found themselves behind just 11 minutes into the contest when Christian Eriksen’s excellent 20-yard strike sailed past the helpless Thibaut Courtois.

However, Antonio Conte’s Blues got themselves back into the match on the stroke of half-time through Pedro, and then took that momentum into the second half, netting through Victor Moses six minutes into the second period.

Moses’ goal proved to be enough to seal the three points for Chelsea, who returned to the top of the table having seen Manchester City and Liverpool overtake them earlier in the day.

It has been quite the turnaround from Conte’s men, who lost against Liverpool and Arsenal prior to winning seven games on the spin.

And it was Chelsea’s defence which let them down in the early stages of the season and, although that area has drastically improved seen then, Conte may still want a couple of players to strengthen his backline.

Thus, here is the dream Chelsea back three, including one key January target…

Cesar Azpilicueta

Spanish international Cesar Azpilicueta has been one of the best full-backs in the Premier League since his arrival in 2012, and he’s seamlessly slotted into Conte’s back three in the last few months.

The 27-year-old has been an ever-present in the Chelsea team this season, and was one of a few players who started the campaign well for the Blues despite their defensive struggles.

Azpilicueta’s natural position of right-back seriously helps him on the right-hand-side of this back three, as he’s able to move wide with the knowledge that one of Nemanja Matic or N’Golo Kante can slot into his position.

He has been a key part of the Chelsea defence that has conceded once in seven games, and he’s likely to retain that importance as the season progresses.

David Luiz

It looked for all the world that David Luiz returning to Stamford Bridge was nothing more than a panic buy by Conte and co, given his previous experience and defensive capabilities at Chelsea.

However, the Brazilian international has been a revelation in the Blues’ back three.

Luiz has significantly improved defensively and is still able to retain possession when needed, and also move the ball up the pitch and launch attacks.

Being in the middle of this back three gives him huge responsibility, which it is something he has taken on admirably so far this season.

Leonardo Bonucci

Chelsea were linked with Juventus defender Leonardo Bonucci when they were embarking on their tricky spell back in September, but it’s still a move Conte should attempt to complete in January.

The 29-year-old has been one of the best centre-backs in world football in recent seasons, and Conte knows all about his qualities from his spell in charge of the Old Lady and indeed the Italian national team.

Although Gary Cahill has improved since Chelsea switched to a back three, Bonucci knows the system and the manager even better, and would be a brilliant signing for the Blues.
