Jose Mourinho has an outstanding selection of players at his disposal but one position that needs addressing in January is his options right-back.
The Portuguese tactician has opted to play Branislav Ivanovic at right-back throughout the majority of Chelsea's opening games of the season, and while he has impressed for the Blues - he is still predominately a centre-back.
Ivanovic does not possess the attacking traits that the Premier League's best full-backs - such as Ashley Cole, Patrice Evra and Leighton Baines - all possess.
Modern day full-backs have to be comfortable on the ball and have the confidence to make surging runs to support his teammates.
One man at the club who is a modern day right-back is Cesar Azpilicueta, however Mourinho seems like he doesn't really fancy the former Marseille man.
In fact, the 24-year-old has been linked with a move to Serie A side Napoli, as former Chelsea interim boss Rafael Benitez is said to be keen on linking back up with the Spain international.
Mourinho may be forced into buying a right-back if Azpilicueta is going to leave for Napoli in January.
'The Special One' and his array of coaching staff will be scouting the whole of Europe if he is going to dipping into the transfer window, but the man he needs is closer to home then he may think.
Southampton star Nathaniel Clyne has acclimatised to life in the Premier League with minimum ease.
The 22-year-old progressed through the ranks at Crystal Palace before joining Southampton, as he wanted to play regular Premier League football.
Southampton beat off the likes of Manchester United, West Ham and Newcastle to sign the starlet and you can see why.
Mauricio Pochettino's Southampton have the best defensive record in the Premier League - conceding just four goals in their first 10 Premier League games of the season - and Clyne has played a major part in their defensive success.
Clyne was linked with a £7m move to Chelsea in the summer but they did not follow up their initial interest in the England Under-21.
However Clyne now has the maturity to move to a top four Premier League team and Chelsea may be the best place for the starlet to continue his education, especially as he could learn from one of Europe's best full-backs in Cole.
