According to a report by Football London on Tuesday November 10, 2026, Chelsea could return to the transfer market when the January window opens, with manager Xabi Alonso reportedly asking the club's hierarchy to strengthen a particular position in his squad.

The Blues invested heavily during the summer, recruiting players including Morgan Rogers, Maxence Lacroix and Emiliano Martinez. Bournemouth midfielder Alex Scott remains a major target, but another defensive addition could also be considered.

According to journalist Simon Phillips, Chelsea are exploring the possibility of signing a centre-back, with Alonso specifically requesting a left-footed defender. The manager reportedly believes this profile would improve his defensive options.

This request comes amid concerns surrounding Levi Colwill's performances this season. The England international has struggled to reproduce the impressive form he demonstrated towards the end of the previous campaign.

His difficulties were particularly noticeable against Sunderland, where he struggled to contain striker Brian Brobbey before eventually being substituted. Meanwhile, defensive partner Wesley Fofana delivered a considerably better performance.

However, Fofana has also experienced inconsistent moments throughout the campaign. His performances have attracted criticism, with one frustrated Chelsea supporter even questioning his involvement after encountering him arriving at the Stadium of Light.

Chelsea had already strengthened their central defence by signing Maxence Lacroix, previously of Crystal Palace. Unfortunately, the defender is currently sidelined with an injury and is not expected to return until January.

His absence has created additional pressure on Colwill and Fofana, who must improve their performances while Alonso waits for defensive reinforcements.

With Chelsea struggling to maintain consistency at the back, recruiting another centre-half could become an important priority. Alonso's preference for a left-footed defender suggests he wants greater balance, competition and reliability within his defensive options.

The January transfer window could therefore provide Chelsea with an opportunity to address these concerns and strengthen their defensive department for the remainder of the season.
