Erik ten Hag’s side sunk to their third loss in their opening five Premier League games as goals from Danny Welbeck, Pascal Gross and Joao Pedro sealed a deserved win for Brighton at Old Trafford.

Agbonlahor blasted Casemiro’s performance in midfield but also hit out at Lisandro Martinez, who was fooled by a dummy by Gross for Brighton’s second goal, and has called for Harry Maguire to be handed a starting place.

‘Where do I start? Brighton had 659 passes at Old Trafford. More shots on target, more possession – 57 per cent. It was a stroll in the park for Brighton,’ Agbonlahor told talkSPORT.

‘I am watching the game, at no time did Brighton ever feel like they couldn’t pass it out from the back.

‘No matter who was pressing, they found it so easy to get through and create chances. That was like a training ground game, especially the second half.

‘Casemiro… Casemiro looked like he was 45 running around that midfield. He had to bring him off on the 65th minute for Hannibal, a young lad, because he was that bad.

‘You know what else wound me up today? Let’s see the same energy for Lisandro Martinez and Victor Lindelof.

‘Martinez for the Gross goal, he has tried to make a block, he’s got fake-shot by Gross and scored in the back of the net.

‘If that was Harry Maguire, you would not hear the end of it, ‘he’s terrible get him out the side’.

‘Harry Maguire must be looking around that changing room now thinking, ‘how am I not getting a chance in this team?’

‘Martinez could not even play from the back, giving the ball away, Lindelof as well. Harry Maguire deserves to be in that team.

‘So let’s see the same energy, all you tweeters, whoever you are, let’s see the same energy for Martinez at the back, for Casemiro, who can’t get around the pitch, not just pick on Harry Maguire.’
