Gary Neville claims Ole Gunnar Solskjaer is now under pressure at Manchester United after losing the Europa League final as the club 'can't switch performances on and off like a tap'.
The Red Devils were beaten on penalties by Unai Emery's Villarreal on Wednesday night after a 1-1 draw which saw Edinson Cavani cancel out Gerard Moreno's strike in normal time.
The result means Premier League runners-up United have failed to win a trophy for the fourth consecutive season, with their last major honour coming in 2017. Neville, who has backed Solskjaer in the past, has demanded his former side spend well in the summer as a good start to next season is needed 'badly'.
The former defender tweeted: 'You can't switch performance on and off like a tap. Haven't played well for weeks and last night a continuation of the form recently.
'Pressure will be applied to Ole and the team. Rightly so. Need to get it right this summer and a good start to next season needed badly!'
Despite Neville's defiance and serious message to the club, he was unable to avoid from Jamie Carragher's jokes, with the fellow Sky Sports pundit and former Liverpool defender tweeting a funny picture of them together for Monday Night Football.
Defeat in the final to Villarreal, which came after David de Gea saw his spot kick saved by Geronimo Rulli after all of the outfield players sensationally scored their penalty efforts, means Solskjaer is still without a trophy as United manager.
The Red Devils finished 12 points behind rivals Manchester City - who also beat them in the Carabao Cup semi-finals as well - while they were knocked out of the FA Cup quarter-finals by eventual winners Leicester.
United boss Solskjaer admits his side did not turn up for the Gdansk final on Wednesday night and has challenged his side to pick themselves up from the agonising disappointment.
He said after the final loss: 'We didn't turn up. We didn't play as well as we can do. That's football for you.
'It's sometimes decided on one kick and that's the difference between winning and losing.
'We've got to, not savour the feeling, but taste it and make sure you don't get it again.'
