We can go on about how many injuries Tottenham have had this season, and that has certainly played a part in their inconsistencies, but they have got a nearly fully fit squad available now and the fans are frustrated by some of the performances and results.
Ange Postecoglou has a philosophy and way of doing things and believes in what he is doing at Spurs. He has snapped a few times at fans and the media, but I think that is more ego and belief in himself rather than pressure.
He has a long-term plan with the personnel and he thinks: 'This is me. I'm going to stand by who I am and what I am doing.' Last season, everybody was excited by Postecoglou and his style but when it turns on its head like it has this season, things can get heated. Fans will understandably be frustrated.
Unless he wins the Europa League this year I don't think he will keep his job with the league position they are in. When managers have a longer-term plan and distinct philosophy it is whether the people above want to buy into that and buy them the players they need, and whether the fans have the patience to buy into that.
I do think Postecoglou would need time. If you look at his first season you can see the direction he was taking the team.
They would need to sign some players in the summer, especially central defenders, if they are to keep him next season even if they do not win the Europa League and want to play his style.
But, you can see the frustration among the fans and the inconsistency in performances and that can become quite difficult to sustain.
