The January transfer window is just around the corner and no doubt Antonio Conte will be looking to bolster his Chelsea squad for the final push of the season.
The Blues brought in five players over the summer, however the Italian spoke several times about the depth of his squad and there is one area in particular that feels that it needs more protection.
Marcos Alonso has so far started every Premier League and Champions League match for the Blues in the left wing-back role and the 26-year-old started the campaign in blistering form, especially the brace against Tottenham Hotspur.
However, his performances have faded somewhat in recent weeks and you can’t help but feel that the minutes are already creeping up on a player that is asked to play in such a demanding role.
There is no back-up to his position, with Kenedy not fancied to step in when needed and no other left-footed option that might be able to even push the Spaniard for the starting spot.
Alonso still has a lot of good things to bring to the team, however he needs someone to come in to either rotate, push him to the next level or even just allow him to have a breather from time to time with such a busy schedule.
The Blues must look to that position in the winter, but who could they possibly bring in?
The 25-year-old is still one of the top left-backs going in European football and would fit perfectly into Conte’s system should he make the move to Stamford Bridge.
It definitely wouldn’t be easy getting him, though, with Bayern Munich likely to want to keep him in Germany or put a massive price on his transfer and a contract that is running until 2021.
He has been with the club since a teenager, but he has the ability to play in the wing-back role and would be a major coup is the Blues could make it happen.
Things seem to have gone downhill for the left-back since his horrific double leg break in September 2015, in a career that had promised so much early promise.
Since his recovery, Jose Mourinho has used him sparingly and has criticised him publicly in what has been a difficult return for the 22-year-old.
This season has been even worse than the last with numerous matches for the U23s and only two Carabao Cup games for the first team, both coming off the bench.
Being a Chelsea fan, no doubt it would be a dream for him to play for the club, but would he be the right man to come in a strengthen the squad?
One of the biggest disappointments for Chelsea and Conte over the summer was the inability to sign the talented left-back and they came up short in numerous attempts to get him
The Brazilian had something of a slow start to his professional career, however is now starting to prove himself as one of the top left-backs.
After playing for several years for Porto, the 26-year-old is now plying his trade with Juventus and is benefiting from playing regular first team football.
Another go at trying to sign him could be on the cards in January, and although Juve want to keep hold of him he is yet to sign a contract extension.
The 28-year-old Champions League winner has turned himself into one of the best English left-backs in the Premier League at the moment and obviously knows the Blues well.
He would be a very safe bet is Conte was able to bring him in, but the issue would be trying to take him away from Southampton, a club looking to dig their heels in at every possibility.
He has a contract there until 2021 and a lot could depend on whether Virgil van Dijk remains with the Saints, as they would not be willing to let two star defenders go in one window.
