We saw a surprise in the EFL Cup semi-final match and it was very interesting and exciting. Arsenal lost the match and they are very likely to be eliminated from the semi-finals. Newcastle played strongly and with excitement which resulted in them achieving a good result to qualify for the final. Newcastle are two goals ahead in the first leg of the semi-final, of course they will be even stronger against Arsenal in the second leg to qualify for the final. I think Arsenal may not be able to score as many goals in the second leg so their chances of going to the final are also very low.

It's a signal if they will be trophyless again this season. The same story happened to them every season. It's hard for them to win the trophy with their current mentality, and the lost against Newcastle proven it.
They're too often depending on their setpiece, but when club has discovered to counter it, they can do nothing. Look at the picture i mentioned above, almost a half of their players lying on the floor.
Also, the moment when Isaack pushed Arsenal's defender to get a space. They know very well how to counter Arsenal.
The better for them to sign Ten Hag, which gave two trophies in two season instead of keep Arteta much longer.
