Chelsea's start to the 2021/22 season has been fantastic – and it was made even better on Tuesday night as they secured their place in the Champions League Round of 16.
The Blues are sitting pretty at the top of the Premier League, but despite this, Thomas Tuchel knows that there is room for improvement in west London.
With the January transfer window looming, it could be a perfect opportunity for Tuchel and the club's board to improve the squad for the remainder of the season, with Chelsea fighting on all fronts.
With that being said, football.london takes a look at the latest transfer rumours coming out of west London, with just over a month until the mid-season window opens.
Azpilicueta contract update
According to Fabrizio Romano, Chelsea are very confident that Cesar Azpilicueta will sign a contract extension in the near future.
The Spaniard sees his deal at Stamford Bridge reach its conclusion at the end of the season, but the Blues are in talks with the experienced defender over extending his stay in the capital.
Romano, when speaking on Rio Ferdinand's YouTube channel, said: “Barcelona will go for this kind of market. I sense they will go for this type of player in June, free agents.
“Azpilicueta, from what I’ve been told, Chelsea are so confident to extend his contract. This is for Azpilicueta and also for Thiago Silva.”
Pulisic wanted by Barca
According to El Nacional, Barcelona are interested in signing Chelsea winger Christian Pulisic.
Liverpool have been linked with the USA international in recent days, but now it seems as if the Reds may have some stern competition for his signature.
Pulisic, who joined the Blues in 2019, is believed to be valued at around €50million (£42m) by Chelsea – a price that could prove to be an issue for Barcelona.
According to ABC Sevilla, via Sport Witness, Sevilla found Chelsea's attitude over signing defender Jules Kounde 'very surprising' during the 2021 summer transfer window.
The Blues were strongly interested in signing the 23-year-old centre-back over the summer, but Sevilla's £68.5m price tag was not met and therefore he has stayed put.
It is not yet known whether Chelsea will reignite their interest in the France international in the January transfer window, but if they do, then Sevilla may demand a similar fee for his services.
