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.
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.
I don't think with Leicester City and Chelsea are difficult team for Newcastle United on two matches left for qualifying to Champion League spot standing season 2023/24. You can see both teams performance on last several matches not consistent and they looks loss motivate for winning on every game exactly with Chelsea.
Manchester City almost close for winning Primer League tittle in this season actually they are on confidence after success defeating Real Madrid and qualifying to Champion League final stage, winning one match left automatically they will win Primer League three time in a row. Interested with top fourth race because Newcastle, Manchester United and Liverpool still has chance for finishing on Champion League spot standing.
