Mathematically, Newcastle have not passed the UCL because they still meet Leicester City, who are struggling to avoid relegation, and Chelsea, who could qualify for Man United or Liverpool.
I don't know how you see it and what kind of calculation is used as a benchmark for whether or not to qualify for the UCL. Isn't it obvious that the top 4 will qualify and now Newcastle has an ideal distance of points to stay afloat. Then with the remaining 2 matches they have that will determine them as a club that passes. Leicester City and Chelsea don't have much hope and both of them will find it equally difficult to conquer Newcastle, so far the strength and solidity of Newcastle's players are superior.
Newcastle game with Leicester City and Chelsea won't be tough at all, this is a game they will have full points that will make them to qualify for champions league next season. Leicester City are in the relegation zone and struggling on how to win their games, Chelsea Is still a struggling team that Newcastle is fit enough to defeat. Newcastle being part of top four in the league have been sealed, I don't think they will lose their position.
@bbigtart, That is a calculation that doesn't make any sense at all because in fact, Newcastle only need one win to ensure a successful finish in the top four. Also, are Leicester and Chelsea in this moment any better than Newcastle? I personally really don't think Newcastle will lose when playing against them in the remaining two matches.
Because after all, Newcastle from the previous season until this season has been consistent with very good performance. So, because Newcastle has transformed very well, at this moment Newcastle has very good quality and also, Newcastle deserves to get a ticket to the Champions League.
