Chelsea are in a state of bother and need reinforcements in the January transfer window. Thomas Tuchel has a big squad, but the last few weeks have proved that the drop in quality on the bench is significant.The Blues have been linked with a few star players this upcoming window. However, the number of transfers that could happen is very likely to depend on how many players first leave the club. Chelsea do not have enough space in the squad to keep adding talent without letting go of deadwood. Tuchel has a busy week ahead as he plans for the window and works on getting his team back on track.Here are 5 players who have been linked with January moves to Chelsea:#5 Eden HazardBeSoccer@besoccer_ES🏴󠁧󠁢󠁥󠁮󠁧󠁿🔙Hazard aceptaría volver a Inglaterra🗞️Según 'The Mirror', el belga estaría dispuesto volver al Chelsea si la entidad de Stamford Brigde lo recibe con los brazos abiertos8:30 PM · Dec 16, 2021103🏴󠁧󠁢󠁥󠁮󠁧󠁿🔙Hazard aceptaría volver a Inglaterra🗞️Según 'The Mirror', el belga estaría dispuesto volver al Chelsea si la entidad de Stamford Brigde lo recibe con los brazos abiertos https://t.co/UnYO4vTpQcEden Hazard left Chelsea in 2019 after winning the UEFA Europa League and sealed his dream move to Real Madrid. He is not enjoying football anymore at the Santiago Bernabeu, and it is mainly down to him not getting enough chances and his unfortunate injury record. Vinicius Jr. is in red-hot form, and Carlo Ancelotti has no reason to drop the Brazilian.Reports suggest the Belgian is open to leaving Madrid, and Chelsea have been linked. The Blues are said to be interested in making a move, but the majority of those reports have come from Spain.None of the reliable sources in England have suggested Chelsea are interested in re-signing their former player in January. Things could change quickly as the Blues need a creative player, and if the Belgian becomes available on loan, the move could be ideal for all parties.Newcastle United have also been linked with a move for Hazard, while clubs in France and Germany are also keeping tabs on him.#4 - Maxence LacroixChelsea FC News@Chelsea_FLChelsea fans split on whether club should go for Jules Kounde or Maxence Lacroix 🤔🔵 #CFC football.london/chelsea-fc/tra…04:30 AM · Dec 18, 2021274Chelsea fans split on whether club should go for Jules Kounde or Maxence Lacroix 🤔🔵 #CFC football.london/chelsea-fc/tra…Antonio Rudiger, Cesar Azpilicueta and Andreas Christensen are yet to pen new deals at Chelsea.
