Two of the three elite clubs that failed to qualify for the Champions League this season have made major overhauls in their squads to aim for a better season than the previous season. Chelsea and Liverpool have brought in several quality players to improve the quality of the team to compete at the top of the premier league standings. Chelsea are quite serious in rearranging their squad, they are doing a major overhaul in the squad as well as bringing in a new coach.
Liverpool who have qualified for the Europa League this season, certainly want to perform optimally, Jurgen Klopp has replaced several players in different positions in order to maintain their chances of being in the top four and hopes of going further in the Europa League. Tottenham which seems too economical to spend money in the transfer market, will experience difficulties this season, the increasingly competitive Premier League makes Tottenham chances even slimmer to finish in the European zone if they don't bring in some great players.
Of course Liverpool, Chelsea and Tottenham will try their best to return to competing in the Champions League next season after they failed to achieve it last season. They have made reforms and improved the quality of their players by bringing in several new players, but even that still doesn't guarantee they will be able to qualify for the Campion League.
Arsenal, Manchester United, Manchester City and Newcastle are teams that have the same potential to be in the top 4 of the standings, but of course that position is contested by at least 7-8 top teams until the end of next season. Liverpool and Chelsea might be able to qualify if they improve but I think we will only get the proof once the season starts.
