Arsenal should learn from previous experience where maybe their players are tired and maybe injured more easily so that at the end of the season it looks inconsistent so the chance to become the EPL champion failed after Manchester City overtook them, this season even Arsenal has two focuses apart from their domestic league they also started to focus on the UCL it is clear that players will tire easily if they divide the two focuses.
It seems Arsenal has learnt from there mistakes last season because they have been shopping for players seriously in the transfer window and has had one of the best transfer window so far, the only club I think has had a better window is Chelsea because they're making profits instead of spending as they are letting go of all the flops that were draining them to the Saudis and making lots of profits from the sales. Arsenal has recruited players that can put up a fight especially in the midfield but that's not enough. They still need to get more players because challenging for the premier league and champions league is going to be a very big tasks on Arteta boys.
Arsenal needs a prolific striker, depending on Gabriel Jesus is not a wise decision. He's Manchester city reject for a reason and the fact that Arteta is depending on premier league reject might turn out to be a great decision or a worst one. A worst one when they finish next season without important trophy but a smart move if they can win the champion league as they have a big game player like Kai Havertz. He's going to give them some champions league moment as he always does but can't deliver on every game day. I hope Arteta has backups because he needs to have them ready shey his initial plans don't give him what he wanted which is to win trophies.
