Arsenal was ahead by 1 goal but Tottenham just scored a goal and the match is now a draw. When we look at the strengths of the two teams, Arsenal is better at the moment, and I think they have a high chance of winning the match.
The first half is almost over, we still have 45 minutes left and I think Arsenal will return to the field much stronger after the conversations within the team during the halftime. Both teams have a chance, but I think Arsenal will win this match

The two teams are playing very well, looking almost equal in power. Arsenal are good with the ball and have been able to press more to create chances. They had good chances to be leading with three goals, one from Nketiah where he would have passed to the other Arsenal player, but decided to shoot himself, it was saved by the Tottenham keeper. The other chance was from Jesus when he collected the ball from Maddison and had a clear one on one shot with the keeper but missed. I hope Arsenal will not regret it.
Arsenal were very unlucky with those two chances in the first half else they would have been ahead of Tottenham in the first half. But both teams has been so physical and clinical with the game which we all expected being a derby game.
What I don't understand is the rationale behind behind Artheta's decision to substitute Rice and Vierra at ones bringing in jorginho and Harvertz. The substitution has affected the Arsenal midfield badly and it's going to cost Artheta the match he was supposed to win.
