Trent didn’t get booed because of his choice to move. Many didn’t understand it but respected his choice (even though I thought it was a bad choice career-wise but a good choice money-wise).
He was booed because he pretended like it was a choice that was up in the air for him until late, and let the club think that as well (or at least, managed it with the club and told us at the last minute).
He probably made the choice before last season started. So there was a bit of two-facedness going on there.
That’s what people don’t appreciate. He could have just let everyone know he isn’t signing another contract and he would have had a nice farewell season.
Salah just make an impetuous choice but he wants to stay, he isn’t agitating for a move.
