Ten Hag took charge of United this summer and lost his first top-flight game in charge on Sunday as the Red Devils were beaten 2-1 by Brighton at Old Trafford in what was a dismal performance, as they prepare to face Brentford on Saturday.
Some have defended the Dutchman – claiming that the club’s players are to blame instead – with pundit Steve Nicol arguing that not even Manchester City’s serial winner Pep Guardiola could turn things around at United.
Former striker Javier Hernandez has urged the United squad to adapt to Ten Hag’s methods while ex-defender Rio Ferdinand has said that there is only one player in the current squad who would be good enough to make City or Liverpool’s XIs.
Goalkeeper Foster, best known for his spells at Watford and West Brom, who also played for United from 2005 to 2010, has now explained how top-flight clubs can beat United this season.
‘When you’re playing someone like Man United you’ve just got to go up against them,’ Foster told TalkSPORT.
‘They have got quality players but if you get up into them they will struggle a little bit and that’s always the way that we tried to approach those games.
‘Going back to Liverpool and Man City, we [Watford] would be scared about trying to get up into their faces, because they have got so much more technical ability to play it round you and if they get behind you you’re struggling full stop.’
Foster then pointed towards Watford’s games against United last season, as the Hornets, who would eventually be relegated to the Championship, beat them 4-1 at home in November before securing a 0-0 draw at Old Trafford in February.
‘The home game was great that we won 4-1 but I’d say it was the away game that was the most telling because we went away to Old Trafford, bearing in mind we were a struggling team last season, but we made a point of getting in their faces,’ he added.
‘The longer the game went on the more Manchester United fans would get onto the Manchester United players’ backs and you could feel this sort of atmosphere and that’s what’s wrong with it at the minute.
‘There’s a little bit of an atmosphere and around Old Trafford where they’re used to winning, they’ve got [Cristiano] Ronaldo back in the ranks expecting to still be scoring hat-tricks and it’s not quite working like that at the minute.
‘Manchester United in general are vulnerable. I watched the game on Saturday and I predicted before the game that Manchester United would lose the game.’
