It was a busy summer for the Blues as Frank Lampard strengthened the squad by signing Timo Werner, Hakim Ziyech, Ben Chilwell, Thiago Silva, Malang Sarr, Kai Havertz and Edouard Mendy.
Several players have fallen down the pecking order at the club following the number of arrivals during the summer transfer window.
According to reports, four Chelsea players are set to leave the club during the January transfer window after falling down the pecking order at the club.
Kepa Arrizabalaga, Callum Hudson-Odoi, Antonio Rudiger and Marcos Alonso are all expected to leave the club in January in search of regular game time.
Just as the summer transfer window was a busy one for Chelsea, the January transfer window is also expected to be a busy one for the Blues as Lampard looks to trim his squad.
