Former England legend Alan Shearer has hit out at Van Gaal for his inability to build a winning team.
United spent over £100 million in transfer this summer, but Van Gaal still sits in fifth and picked up seven points from four games.
Shearer has accused Van Gaal of playing drab football and stresses that the match against Liverpool is a must win.
“I would argue Louis van Gaal cannot even afford to draw the game against Liverpool,” Shearer writes for The Sun.
“He has been asking for more time for his team to blend, for young players to develop etc. Time is up I’m afraid – the time is now.
“You cannot oversee the changes he has made, backed by hundreds of millions, and then claim you are a victim because it needs time to blend. It is your job to mould a side and I would suggest a year is plenty for a club of Manchester United’s standing.
“You can get away with the dull, functional football Van Gaal is dishing up if you are getting results. But if you go back to the end of last season, Van Gaal’s league run over the last 10 games now stands at three wins, three draws and four defeats.
“Van Gaal’s CV has afforded him the time that David Moyes was not given. But a poor result on Saturday and questions will start to be asked.”
