Chelsea's Kai Havertz says contracting Covid-19 hit him "very hard" and he now understands how difficult the global pandemic has been for others.
Germany international Havertz, 21, tested positive in November and said he spent seven to 10 days "just in my bed and everything was hurting".
Havertz missed three games with the virus but has started Chelsea's last three games in all competitions.
Havertz said it took him two or three weeks but he is now "very fit again".
Since joining from Bundesliga side Bayer Leverkusen for £71m, Havertz has scored three times in 16 appearances - netting a hat-trick against Barnsley in the Carabao Cup.
