The Blues have lost back-to-back matches and are in danger of falling off the pace in the Premier League title race
Chelsea head coach Frank Lampard has said some of his club's new players need to "wake up" after back-to-back defeats to Everton and Wolves.
The Blues were flying high to begin the Premier League campaign but losses at Goodison Park at the weekend and Molineux on Tuesday have brought them back to earth.
The club spent big in the summer on a handful of new players and though some, like Thiago Silva, have slotted in seamlessly, others, like German duo Kai Havertz and Timo Werner, are currently struggling for form.
