It might be different for Klopp, but I don't expect Liverpool to be able to defend the title next season. They were lucky that everything worked out in their favor this past season which enabled them to win the title. Nex season might be different, because many clubs have bought new player and some clubs that were in a poor form last season based on injury will pick form next season.
Predicting who will win the Premiership or clubs that will be in top four at this time will be difficult. We have seen several clubs buying new players and even Liverpool is not left behind. They recently broke Premiership club recods to sign Florian Wirtz. The German will be a great addition to the club which would help them to fight to defend the trophy. When it comes to injuries, it is highly unpredictable, we just have to wait to see if Liverpool will be able retain the trophy.
