Manchester United are also a very interesting team this season. "Inconsistent" might be a better word to tell their condition I guess. They can win against Chelsea at Old Trafford but at the same time they can lose to Bournemouth at the same place by even a huge score like 3-0.

The point difference with top 4 is 6 now. Finishing the season in top 4 will be crucial for Erik ten Hag. If the board don't see the team in the Champions League next season then I don't think Erik ten Hag would stay longer.
I'm talking like he will last until the end of the season of course. Who knows maybe he would get sacked earlier depending on results.
