Mudryk, who did not play a part in the Blues' last two matches and had made only one appearance in November, was absent from Enzo Maresca's training session ahead of the club's upcoming Europa Conference League match against Astana on Thursday. Per Football.London, the Ukrainian is suffering from an illness and is not part of the travelling squad. Journalist Simon Johnson further claimed that Joao Felix has also picked up an injury and was not included in the team heading to Kazakhstan. In the absence of two key members, Maresca has named several academy players in his roster.
