I’ve seen many fans and pundits make this claim. Do you think Manchester United players aren’t playing as well as they can in hope to get Ten Hag sacked. I’ve seen this argument used against Rashford as people since he’s got his new contract he’s just content to get his money and play as well.
Though Hoijund has claimed the players all back Ten Hag still https://www.theguardian.com/football/2023/nov/09/erik-ten-hag-manchester-united-squad-backing-rasmus-hojlund
That could be due to a number of factors, first of all Klopp had a huge amount of good will from the Liverpool fans built up which ETH hasn’t had the time to do yet. ETH also has a habit of making some fairly strange decisions both in game and in the starting 11 even for positions that don’t have bay injury worries which provides ammunition for anyone who doesn’t want him, he also seems to struggle a bit with man management which for a team that has so many divas in it can cause issues. Regardless of that I think that anyone who wants him sacked is making a rash decision.
