The competition for tickets to the Champion League is indeed very fierce, especially for several teams that have a fairly small difference in points so that it is possible for shifts to occur every week, but if you look at the last few weeks in the matches of all the teams competing at this time, I think Newcastle has a large percentage to be able to get a ticket to the Champion League next season.
Newcastle does have the opportunity to secure a ticket to the Champions League because based on statistics from several previous matches they are much better than several other teams. Even so, Man City and Nottingham Forest also have a good chance of securing a ticket to the Champions League because Chelsea and Aston Villa are not as consistent as the two teams.
Although there is no guarantee, I am more confident that the team will qualify for the Champions League because Chelsea and Aston Villa made too many mistakes in several previous matches so it is much more difficult to maintain consistency in the remaining matches.
