The club added that he is “doing well and looking forward to returning to the training ground as soon as it is possible”.
Hudson-Odoi posted a video on Twitter in which he said: “As you may be aware I had the virus for the last couple of days which I have recovered from.
“I am following the health guidelines and self-isolating myself from everybody for the week. I hope to see everybody soon and hopefully will be back on the pitch very soon.”
Thank you for all your good wishes, as I said in the video I’m feeling good and hope to see you all soon!!🙏🏾❤️ pic.twitter.com/hn5d0ikm60
