How do you mean five teams will qualify for champions league next season I don't understand, you said Liverpool, Arsenal, Nothingham forest, Manchester city and Chelsea how? Remember the fourth position is not certain for now and also remember that Newcastle has an outstanding if they should win the outstanding it means they will be at the fourth position and if they maintain it, they will be fortunate to qualify for champions league and so the three team that are fighting for the fourth position is Newcastle, Chelsea and Manchester city I mean these are the teams that have the more chance of competing there.
Normally the Premier League has 4 tickets for the Champions League but there will be 1 additional ticket which can be obtained from 3 competitions UCL, Europa and Conference League so the Premier League teams managed to take their place there so they get 1 more ticket, you can find this news published yesterday. If in the end the Premier League has 5 tickets to the UCL then Manchester City has a chance to get it who will compete with 3 other teams such as Chelsea, Newcastle and Aston Villa.
By the way did you know there is a potential for an additional 2 tickets to become 7 tickets if a team from PL win the Europa League and Aston Villa wins the Champions League, yeah even though it sounds impossible but the possibility is still available.
