Buying new players does not make City any ready for the new season, I only shows they are consciously making preparations for the new season, they will need more than buying of this new player to show that readiness and do not forget that you can have all the players and still not be as ready and may even still be behind other teams when the season eventually starts. Liverpool needs that replacement els they will have to make a substitution using the alternative or making one of their attackers a false striker.
Buying lots of new players in the transfer market does not guarantee that a club will have a good season next season. Because well, preparation is just preparation. We still can't guess whether it will be successful or not before the season actually starts and the team shows quality in several matches. But Man City, with their current preparations, actually looks like they will make the new season better for them. I'm sure Man City won't want to experience a bad season again. Man City will try to restore their dominance in the Premier League. Liverpool is the same. But I hope there will be surprises in the new season. Namely, I hope that a team that we don't expect will succeed in dominating the league from start to finish. And that would really shake up all the big teams.
