Mudryk has also received the backing of Maresca, who told reporters last month: ‘We support and we trust Misha.
After his positive test was announced, Mudryk posted on Instagram: ‘I can confirm that I have been notified that a sample I provided to The FA contained a banned substance.
‘This has come as a complete shock as I have never knowingly used any banned substances or broken any rules, and am working closely with my team to investigate how this could have happened.
Mudryk, 24, is currently suspended from playing football after it was confirmed last month that he had tested positive for the banned substance Meldonium.
He has denied any wrongdoing and vowed to prove his innocence, but has not played for Chelsea since November.
Following reports that Bert and McKennie jetted off on a getaway together, with the pair both posting photos from the popular French ski resort, Courchevel, Bert showed off a handwritten card she had received, which had the name of the sender curiously concealed.
‘I know that I have not done anything wrong and remain hopeful that I will be back on the pitch soon. I cannot say any more now due to the confidentiality of the process, but I will as soon as I can.’
Bert and McKennie have been following each other on social media since October, and now appear to be dating
The card read: ‘Enjoy baby, Love. Merry Christmas.’
‘And I have never confirmed any relationship!’
Bert and McKennie both posted photos from the French ski resort, Courchevel, before McKennie deleted the snaps from his Instagram
But he has been unable to live up to expectations, and was largely restricted to substitute appearances in the opening months of the season under Enzo Maresca.
The name on the card would appear to be ‘Weston’, but Bert has since taken to her social media account – which boasts 779,000 followers, to deny links to the American.
Meanwhile, Mudryk arrived at Chelsea in a deal worth £88m in January 2023, and much was expected of the Ukrainian star.
‘Trust means that we believe Misha. We support Misha and then we see. We are all sad. Me, the club, the players, we are all there.’
