Where do you start with this one? New United boss Ten Hag was left in no doubt regarding the side's problems when a Pascal Gross double sent them crashing to an opening-day defeat last week.

But not even the most pessimistic United follower could have predicted their collapse in west London, as Ten Hag became the first Red Devils manager to lose his first two games at the helm since John Chapman in November 1921.

Things got off to a dreadful start when David de Gea let Josh Dasilva's shot squirm into the net after 10 minutes; since the start of the 2018-19 season, only Jordan Pickford (11) has made more errors leading to Premier League goals than the Spaniard.

Mathias Jensen, Ben Mee and Bryan Mbeumo joined Dasilva on the scoresheet by the 35th minute as Brentford scored with their first four shots on target, while Cristiano Ronaldo cut a dejected figure on his return to the United team.
