Yup I didn't know that a week ago he was made permanent by Chelsea with 45.5 million Pounds for a long-term contract and indeed I was left behind about this because indeed the rumors were a little covered with other rumors especially when discussing some other star players so I missed this player transfer 
Hopefully this choice is right for Joao but indeed at least with Joao at Chelsea, the quality of their attack could be better this season even though now Chelsea's midfielders and attacking players are too piled up.

Of course this match will be very interesting where Arsenal and Brighton, who at the beginning of this season, seem to want to make their performance conditions continue to improve with the wins made and they have to beat each other in this match.

But looking at the conditions now I don't think this will be easy for Arsenal even though they are still very favorite because of the superior quality of players and playing home but we can see that in the first 2 matches Brighton's performance is quite good.
Both clubs also have quite good productivity in the first 2 matches so I think this will be more interesting where surely both clubs can score goals although I will bet on Arsenal in this match.
