Newcastle just got what they wanted to get the got the ticket for champions league even if they didn't have enough potential for it.
But for the next season, I don't think Newcastle can stay on top of the table.
Next year is expected to be harder for every team but this doesn't mean that Newcastle are any lower comparing to the others. In fact Newcastle are trying to consolidate the team especially after money joined their management.
Manchester United are doing the same too. Liverpool and Chelsea are trying to repair the damage done this year. Spurs are useless whatever they try. The other teams aren't that bad but I don't think if they could compete top teams.
