Newcastle United boss Rafa Benitez feels for Sam Allardyce over this week's survey at Everton.
Allardyce was not happy when his club asked a fan panel to give him a mark out of 10 earlier this week, later receiving an apology from chairman Bill Kenwright.
Benitez said: "It was a massive mistake.
"I don't agree with him on a lot of things, but on this one it is obvious it was a mistake.
"You cannot be talking about that, especially when things are not going so well. It makes no sense, the club were wrong."
