It's not a crime to change your mind, but to do so very quickly can sometimes make you look a little foolish.
And Arsenal fans have picked up on the fact that Sky Sports pundit and former Gunner Paul Merson has very quickly changed his tune on what the club should do with Alexis Sanchez and Mesut Ozil.
Back at the end of November, Merson tipped Arsenal to finish in the top four ahead of Tottenham and Liverpool if they kept hold of the contract rebel pair in January.
"I think Arsenal will make the top four, but only if Alexis Sanchez and Mesut Ozil both stay in January," he wrote in his Sky Sports column .
"But if they do not, then that top-four order will change again as I would not give them a hope of making the top four."
Fast forward 16 days and three disappointing results against Manchester United, Southampton and West Ham, and Merson has changed his tune.
"Nothing has changed at Arsenal," he said ahead of the Gunners facing Newcastle this weekend.
"We are 17 games into the season and they are below Burnley. That is embarrassing. You can understand after five or six games, if someone gets off to a flying start, but this is 17 games in.
"I don't know where Arsenal are going. I have said before that Alexis Sanchez and Mesut Ozil will probably stay but now I think they have to go because they are doing nothing."
So from needing them to stay in January two-and-a-half weeks ago to needing to get rid of them because they're "doing nothing" now.
Make your mind up, Paul!
