Next season Newcastle will appear in the Champions League so Newcastle need to increase their strength so they can compete with other strong teams.
Newcastle have got several new players to strengthen their team this season. there are even rumors that they are also eyeing bringing in the AC Milan team manager, Andrea Romeo. Newcastle seems quite optimistic about this season.
as well as in the Premier League for next season where several teams that were maybe a bit weak will become strong again next season.
some teams might get stronger, my estimate is that teams like MU and Chelsea will show better performance than last season.
whereas Tottenham might suffer a dip in form if a player like Kane agrees to leave them. Rumor has it that Munich has made a final offer to Tottenham. if it is still rejected, maybe Tottenham will still be like last season.
