Frank Lampard issued a stark warning to incoming Chelsea manager Mauricio Pochetinno after a humiliating night for the interim boss at Old Trafford.
After a run of just one win in nine games since Lampard took caretaker charge back in April, the Blues were out to halt Manchester United's quest for a top four finish on Thursday night. But despite missing glorious first-half chances through Mykhaylo Mudryk and Kai Havertz, the visitors were blown away as Erik ten Hag's men ran riot.
First-half goals from Casemiro and Anthony Martial were supplemented after the break by a Bruno Fernandes penalty and Marcus Rashford's late strike. A solo effort from Joao Felix before the final whistle failed to mask Chelsea's latest horror show, leaving the side 12th in the Premier League table going into the final day.
