The Manchester United boss must act quickly after his side's 4-0 loss to Milton Keynes Dons, according to the former Spurs and England manager.
After United's shock 4-0 loss to Milton Keynes Dons in the Capital One Cup last night, the ex-Tottenham boss says 'nobody cares' about the reasons Van Gaal puts forward for the defeat.
As far as Venables is concerned, the Dutchman shouldn't be talking about 'needing a year to rebuild,' he needs to act now.
The former Spurs coach, who also managed Barcelona and England, says the 4-0 defeat was a shocking result and that the only way back for Van Gaal is to be bold and keep faith in the team he selects, rather than make excuses.
"Last night’s result was unbelievable, shocking," Terry Venables wrote in the London Evening Standard.
"Louis Van Gaal talks about injuries and needing a year to rebuild but quite frankly nobody cares, they’re just excuses and Manchester United have to be bigger than that.
"Right now he has got to do one thing - and do it quickly. He’s got to restore the United last-minute-goal mentality that became Sir Alex Ferguson's trademark.
"He has to prove he is The Bold One, that he is prepared to deal with the current situation head on and that, above all else, he has total faith in the 11 players he puts out on the pitch."
Meanwhile, a report in the Standard also details how Manchester United's players are reportedly intimidated by Van Gaal's approach to training.
A player is said to have told 'a close pal': “Van Gaal stands on the sidelines and does a lot of shouting and bawling.
“It’s been an eye-opener and not what we expected at all. Sir Alex knew how to use the hairdryer but this is on full blast. The trouble is, it’s not working.”
United travel to Burnley for their next Premier League this Saturday lunchtime. Van Gaal's men are yet to win this season, having lost and drawn their opening two league games and been knocked out of the Capital One Cup by MK Dons.
