Man United great Roy Keane has been disappointed by the way his former side have started the new campaign.

Former Manchester United captain Roy Keane believes manager Ole Gunnar Solskjaer will get the sack if the English giants do not secure a top four spot in the Premier League this season.

United finished third in the English top flight last term and were able to reach the semi-finals of the Europa League but they often look like a mediocre side as they lack consistency in their performance.

They suffered a shock defeat to south London club Crystal Palace in their first Premier League match of the 2020-21 season but were able to seal a dramatic win against Brighton over the weekend.

However, United legend Keane says Solskjaer needs to step up as the 'honeymoon period is over,' adding that 'the pressure is on now'.

When asked whether Man United could sack Solskjaer if he doesn't secure a Champions League spot, Keane told Sky Sports’ Monday Night Football: ‘Yeah, I think so.

‘You’re a Manchester United manager. If they can invest in the next week with one or two signings… but if they don’t, it’s tough days ahead for United.

‘The remit will be different for Ole this year. Last year it was all about getting top-four.

‘It will be higher this year. They need to get closer, the points total can’t be the same.

‘Ole needs to get his hands on a trophy because the honeymoon period is over. The pressure is on now.’
