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.
Bringing in new players does not guarantee that next season a team's performance will immediately improve, but what must be realized is that it is a step that must be taken for other possibilities, the top Premier League teams have prepared to improve their strength to cover next season and of course no one knows for sure what will happen but at least there will be changes that occur when a team makes changes.
I quite agree with you because bringing new players does not guarantee the rapid improvement but I am very much confidence if the player bought are very strong one and can easily adapt it will be a great advantage to the team, they will have chances of performing excellently at the beginning. I'm also in support of Liverpool make it very early because training together before next season begins it will make things easy for them to get adopted and also for the coach, it will help him to identify the strength of each player and what they can do.
As regard to City at least the effort they are making is quite interesting and also getting players is also a sign that they are really preparing, I don't just know what is their problem but the players look very strong, but I trust Pep Guardiola is going to put more effort this time because his name has been painted black which he need to correct throughout his remaining two season as Manchester City head coach.
