Arsenal's lacklustre performance at Old Trafford has drawn plenty of criticism.
Predictably, it prompted another
Twitter outburst from Piers Morgan, who once again demanded that Arsene Wenger left the club.
And it now seems Paul Merson also believes Wenger should be sacked - if the Gunners miss out on the Premier Leagie title to Tottenham or Leicester City.
"If Man City don't win the league and Tottenham or Leicester do then Arsene Wenger has to go," the former Arsenal midfielder told
Sky Sports .
"If you're sitting there telling those fans - loyal Arsenal fans - that they don't need any new players at the start of the season and then you don't win the league in front of Leicester or Tottenham then I don't see how you can justify it.
"If Man City win the league he can turn around and say 'they've got all the money in the world and can go and buy whoever they want, so would whoever I bought have made much difference?'
"But if Leicester or Tottenham win the league after he said they didn't need any players then I don't see how he can keep his job."
"They went out on Sunday with an attitude of 'it's only Man United and they've got loads of injuries and kids playing, so we'll breeze through this game'," Merson added.
"It just frustrates me and it absolutely does my head in.
"People point to the players, but the manager has to get the players up for these games. Man United might be fifth and not having a good season, but it's still Man United in front of 75,000 people."
Arsenal remain five points behind Leicester with 11 league games left.
