Arsenal is on fire. It's going to be an exciting game against Porto, but I don't think that Arsenal will mess it up. However, the game against Brentford was closer than it should have been considering how dominantly Arsenal played. They are now behind against Porto and they should make sure to take advantage of their chances during the game. It could have gone wrong against Brentford, which truly is just one of the weaker teams in the Premier League.
I can't recall when the Premier League was so close and exciting the last time. It has been a fierce fight between Liverpool and Manchester City quite often, but now it's a tough race between three top clubs. Now all eyes will be on the game between Liverpool and Manchester City. Arsenal is the winner of the weekend already, no matter how the Sunday games end.
Arsenal are indeed in good spirits but it doesn't seem to be comparable to their performance in the Champions League, in the Premier League they appeared fierce while in the Champions League they seemed to have stage fright.
Arsenal is currently just waiting and hoping for a draw between City vs Liverpool to rise to the top, we just have to see what the two top teams will show, but I think City will win
