Chelsea have reportedly been linked with an interest in signing Sergino Dest from Barcelona ahead of the January transfer window. Thomas Tuchel is currently on the lookout for reinforcements at left-back due to an injury sustained by Ben Chilwell.Dest fits the bill perfectly for Chelsea since he can feature in both full-back positions, with Barcelona also keen on raising funds to register the imminent signing of Ferran Torres. The full-back, who made the switch to Camp Nou from Ajax in 2020, made 41 appearances across all competitions under Ronald Koeman in his first season. However, the Dutchman has now endured a dip in form and is unlikely to feature prominently under new manager Xavi. As such, Barcelona are believed to be open to the idea of cashing in on Dest.With reports emerging that Chelsea could be a potential destination for the 21-year-old, the Blues' fans on Twitter refused to stay calm.

Thomas Tuchel's men have registered just one win from their last four Premier League games.Due to their lackluster run of form, Chelsea have also slipped to third in the table. Meanwhile, Manchester City and Liverpool have opened up six and three point leads respectively at the top.Although Chelsea bounced back with a win over Brentford in the League Cup during midweek, they now face a stern challenge on Sunday. The west London club face a buoyant Aston Villa side away from home during their Boxing Day clash. Villa have been excellent following the appointment of Steven Gerrard, winning four out of their last six league games. Their defeat to both Manchester City and Liverpool during that time was narrow and shows how far they've come as a unit. Undoubtedly, Chelsea are expected to have their work cut out against the hosts at Villa Park on Sunday. Another frustrating evening of dropping points may bring an end to their title aspirations.
