Wounded Chelsea have now won just one of their last five Premier League matches after a frustrating recent run continued on Monday night.
Looking to bounce back from a damaging sequence of three defeats in four games that included a listless 3-1 London derby loss at Arsenal on Boxing Day, the Blues went ahead in the first half at Stamford Bridge courtesy of Olivier Giroud’s header.
However, Chelsea – who showed six changes for their second fixture in 48 hours – were pegged back just five minutes after the interval thanks to another strike from the in-form Anwar El Ghazi.
The result means Chelsea sit sixth, behind fifth-placed Villa on goal difference ahead of Sunday’s clash with Manchester City.
That match could now be in jeopardy after a Covid-19 outbreak in the City camp led to the postponement of Monday’s meeting with Everton at Goodison Park.
