Former Aston Villa striker Agbonlahor branded Man United "amateur" during their 4-0 loss to Brentford
The Reds Devils are bottom of the Premier League table after two defeats from two.
Their latest came on Saturday against Brentford during which Gabriel Agbonlahor commentating on the game described the Old Trafford club as "amateur " and players like Christian Eriksen, David de Gea and Lisandro Martinez as "not good enough"
Manchester United face Liverpool on Monday night in the Premier League and Anfield boss Jurgen Klopp has move to the defence of Erik ten Hag's side in response to Agbonlahor's comments.
"It was obviously not a nice week for United after the Brentford game. We forget in these moments how good Brentford are. It [the reaction to it] was that bad, I drove home after watching the first half here [at the training ground] and I listened to talkSPORT and Gabby [Agbonlahor].
"He lost against us 6-0 in my first year, so I couldn't remember him as a mentality monster on the pitch then - but what he said about Man Utd in that show, I was close to calling in and telling him: 'You forgot completely that you were a player'.
"And if ex players go already like this, you can imagine how everything else is going. You have to ask yourself how you want to react in a situation like this."
What Agbonlahor said about United
Agbonlahor did not hold back in criticising United during their 4-0 defeat at Brentford - which saw them go four goals down in 35 minutes.
"If I was them [United] now after this game I'd be thinking, 'You know what, Ten Hag, just pack up'," the former Aston Villa forward said. "He's had pre-season and they have started the season as a shambles, they're like strangers on the pitch.
"If I was Gary Neville now at half-time [commentating for Sky Sports] I'd throw the white towel in and say, 'Alright, it's 4-0, I can't take any more'.
"They're not United, they're divided, none of them are working for each other. Look at them, they're like strangers on the pitch."
