Paul Merson admits he has been shocked by Mason Mount’s struggles at Manchester United given he was ‘unbelievable’ at Chelsea.

Mount established himself as a key player at boyhood club Chelsea after being given his first real chance by Blues legend Frank Lampard.

The midfielder made at least 50 appearances in three successive seasons at Stamford Bridge and helped Thomas Tuchel’s side win the Champions League in 2021.

Mount confirmed he was leaving Stamford Bridge in an emotional social media post in the summer of 2023 after spending 18 years at the club.

Manchester United emerged as the frontrunners to secure Mount’s signature and ended up bringing him to Old Trafford in a deal worth £60m.

Much was expected of the England star, especially after he took the No. 7 shirt previously won by all-time great Cristiano Ronaldo.

But Mount’s first season at United was hindered by injury issues and he continued to struggle last term, scoring just one Premier League goal.

Fortunately for Mount he appears to still have the support of under-fire Manchester United boss Ruben Amorim, who has used him in five of the club’s opening six league games this season.

But Mount faces a major battle to revive his Old Trafford career, particularly following a summer in which attacking midfielders Matheus Cunha and Bryan Mbeumo arrived at the club.

Merson says Mount has ‘probably had two good games’ for Manchester United and believes his struggles highlight the pressures of playing for the Red Devils.

‘I don’t think people understand how big the club is,’ Arsenal legend and ex-England winger Merson said on The Good, The Bad & The Football podcast.

‘They get signed for big money and they come in. I’m a Chelsea fan and Mason Mount was unbelievable for us, unbelievable!

‘He goes to Man United and he’s probably had two good games in two seasons and can’t even stay fit.’

Mount was used as a late substitute in Manchester United’s 3-1 defeat to Brentford on Saturday.

Despite a poor start to the season, United appear ready to stick with Amorim and have dismissed rumours they have already started lining up replacements for the former Sporting manager.

Discussing Amorim’s prospects, Merson added: ‘I don’t like seeing managers getting sacked but there’s just no flexibility is there?

‘He plays this system but he doesn’t have the players for it. You can play players out of position when you’re at Sporting because you’re not playing against top teams week in week out and that’s what he’s underestimated at United.’

Manchester United legend Paul Scholes, meanwhile, admitted he would not have been surprised had Amorim lost his job in the aftermath of the Brentford loss.

‘We talk about Ruben Amorim and his job and we all say we don’t like seeing managers get sacked,’ said Scholes, who lifted 11 Premier League titles during his time at Old Trafford.

‘But if he got sacked yesterday, we would all sit here and probably be thinking it felt like time.’

Manchester United’s patience with Amorim will truly be put to the test if they fail to beat newly-promoted Sunderland at home next weekend.
