Temperatures soared in England today and no one was feeling the heat more than Manchester United's latest manager, Erik ten Hag.

On another humiliating day for a massive club in freefall, United conceded four goals in the first 35 minutes and were swept aside in a 4-0 loss at Brentford in the Premier League.

It's two matches, two losses so far for Ten Hag, the Dutchman who arrived from Ajax in a bold offseason appointment as United's fifth manager in nine years and looked shell-shocked in the dugout as the goals poured in at Brentford Community Stadium.

It was understandable, too. United had never gone into halftime of a Premier League match trailing 4-0. Never before in the Premier League had United conceded so many goals so quickly.

There were so many individual mistakes — goalkeeper David de Gea let a weak shot dribble underneath him for the first goal, Christian Eriksen was tackled inside his own box prior to the second, and Brentford had two free headers at a corner for the third — that Ten Hag probably wanted to change most of his team at halftime.

He made three halftime substitutions, with Cristiano Ronaldo — back in United's team after an offseason when he pushed to leave the club — staying on and playing the full match. He wore a frustrated look throughout.

"What I asked them to do was play with belief and take responsibility for their performance," Ten Hag said. "That is what they didn't do."
