David Beckham gives his verdict on under-fire Man United boss Erik ten Hag as the Red Devils legend reveals one of the secrets behind the 1999 Treble-winners' success

David Beckham offered his thoughts on Manchester United's under-fire manager Erik ten Hag, with the Dutchman's future a constant topic of debate of late. 

Ten Hag enjoyed an impressive first spell in English football, winning the Carabao Cup and guiding the Red Devils to a third-placed finish and a Champions League spot in 2022-23. 

However, things have not quite gone to plan this season, with the club facing the prospect of a campaign without Europe in 2024-25 after a run of below-par performances. 

As such his position has been in the spotlight with increasing regularity, with his side facing a tough run-in with Arsenal up next on Sunday. 

Beckham, speaking at a premiere event in Manchester for Amazon Prime's new '99' documentary, detailing the stunning Treble campaign from 1998-99, has offered his verdict on Ten Hag. 

'We all know that Erik's a very qualified manager and a good manager and he has the right motives,' he told talkSPORT on Thursday night. 

'But I think we were lucky in our day that we had Sir Alex Ferguson, we were lucky that we had Eric Harrison and Jim Ryan and Nobby Stiles and all of these great managers and motivators.'

While Ten Hag has endured a trying second season at the helm, he has still maintained his strong domestic cup record by guiding his side into the FA Cup final. 

United will face arch-rivals City in the Wembley showpiece, with a chance to avenge the defeat in the same stage of the competition last season. 

That game also saw City earn the second of their three pieces of silverware to match United's most prized accolade of winning the Treble. 

For Beckham, though, there should be no questioning his former side's motivation heading into what is undoubtedly the biggest game of their season - and the former England skipper suggested that the ability to maintain that commitment was vital to the team of 1999's success.  

'I think that's the whole point of being a Manchester United player and playing in these big games, you should be motivated,' he added. 

'When you're a professional footballer and you're doing the job that you love and you're at the club that you love, when you're playing in any game whether it's a regular season game or whether it's an FA Cup final against your rivals, then that should be enough motivation.

'If it's not, then you're in the wrong team and you're playing the wrong sport so I think at the end of the day, we went into every game whether it was a youth cup game, a friendly game, off-season or the European Cup final, with the same mentality and the same drive.

'That's what you'd hope at any team and any player for Manchester United, go into an FA Cup final against Manchester City with enough motivation that a manager shouldn't have to say much.'

Beckham was one of a number of Man United legends in attendance at Manchester's Printworks for the premier of Amazon's upcoming documentary. 

The three-part series first airs on May 17, and features archive footage and exclusive interviews from the likes of Sir Alex Ferguson from that seismic season.
