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.
From which mathematics do you express mate? Newcastle even has the capital to continue to defend itself in the top three standings, whose position is in the UCL zone. And the two teams that Newcastle still have to face are teams that are not so strong this season so that Newcastle's chances of settling in the top three in the standings are far greater than Manchester United, who actually still have to fight for victory in the remaining three matches.
This season is more exciting in the fight for the UCL zone because it is getting fiercer than the fight for the EPL title because Man City has been confirmed as the Champion with only one more win. Newcastle needs one more win in the remaining two matches, Man United needs two wins in the remaining three matches and Liverpool wins and gets an additional 6 points, and it is mandatory to win in the remaining two matches. I see here that it is Man United who is under great pressure because there are still big match matches against Chelsea and Arsenal plus the FA Final match against Man City.
Manchester City is comfortable enough and no longer has so much pressure in the remaining matches in the Premier League because Manchester City only needs to beat one of the three teams they will face at the end of this season. Apart from that, what is still interesting to watch are the three matches that Manchester United still has because Manchester United needs to win two of the remaining three matches so that the top four positions in the standings belong to Manchester United at the end of the season. Because Liverpool will definitely try to win in the two remaining matches for them this season.
