In the end they had to share 1 point in this match even though this was still quite good for both teams but I think if the red card did not happen then Arsenal might get 3 points in today's match.
Arteta recognized the tactical changes that the Brighton coach was was making I knew that if he did not increase his defensive line brightening would have found a way to score a late winner just like they did last week against Manchester United. The red card against Declan Rice was a bit harsh because in the first half of the game João Pedro kicked the ball away after the referee had blown the whistle but did not receive any booking for it. It is a bump in the road for Arsenal who would not have expected to be dropping points at this point but picking up one point from this game can still be considered something good. the bad news is that Declan Rice will not be available for their game against Tottenham which is always tough.
The red card received by Declan Rice had a big impact on Arsenal's performance in the second half, they couldn't develop their game anymore and overall getting a draw after playing with 10 players in the second half I don't think it's a bad result for Arsenal.
And for the next match against Tottenham without Declan Rice I don't think it's a big problem for Arsenal.
And what is in the spotlight now is Brighton's performance at the start of this season, it is clear that Brighton's team strength at the start of the season is quite impressive and also this identifies that Brighton is stronger than last season, they only need to maintain the consistency of their performance to stay competitive at the top of the Premier League standings.
