Chelsea head coach Frank Lampard believes Kai Havertz will be in contention to face Rennes on Tuesday after missing two weeks with the coronavirus.
The 21-year-old got a positive test for Covid-19 shortly before the last Champions League clash with the French club and he was self-isolating at home until last week.
It is understood that the £62 million signing from Bayer Leverkusen has been training at home on an exercise bike after recovering from mild symptoms associated with the virus.
