No one can predict what will happen next season. However, I believe Liverpool might be affected if they don't get a good striker to replace Jota. City has bought three new players to add to the squad. That shows that they're ready for next season. Arsenal will also be the runner up club, because they lack a good center forward.
It is true that of course we will not know what will happen next season because of course many clubs are currently doing activities so that they can make their strength better in the coming season. Liverpool would indeed be better if they could bring in a replacement for Diogo Jota because indeed if there is no replacement player for Jota at Liverpool, of course there is a possibility that Liverpool's strength will decrease. but until now there has been no official replacement for Jota and yes of course Liverpool must also be good at choosing who is worthy of replacing Jota's position. but there are also rumors that Liverpool are eyeing Joao Pedro, let's just see what happens later.
yes Manchester City has prepared good new players and of course this will make Manchester City ready to face next season. but Arsenal of course in my opinion he is also good enough for next season to compete for the EPL trophy with some of their new players such as Norgaard, Zubimendi and Kepa and of course Arsenal is still in the negotiation stage to bring in other new players. so of course in my opinion Liverpool must really bring in a replacement for Jota if they want to defend their title in the EPL next season.
