Hakim Ziyech made his £33m transfer fee look like a massive bargain in a costly summer for Chelsea.
The winger from Ajax stole the show at Stamford Bridge on Saturday evening as Sheffield United could not cope with him.
Frank Lampard 's side came from behind to win 4-1 in west London thanks to goals from Tammy Abraham, Ben Chilwell, Thiago Silva and Timo Werner.
Ziyech provided assists for Chilwell and Silva with his expert delivery from two set pieces.
And he certainly filled the void left by Kai Havertz, who missed out due to his positive test for Covid-19.
Heading into the international break, things look a lot rosier for Lampard and Chelsea, and Daily Star Sport has the player ratings from Saturday's showdown with the Blades below.
Eduoard Mendy: Frenchman conceded for first time in Premier league action but otherwise a quiet night. 7
