I actually agree with some people saying that Newcastle's performance started to look strong last season but if we talk about the champions league I don't think Newcastle will be that strong.
One thing we have to remember that the champions league is a very strong competition from big clubs like Bayern munchen, Real madrid, PSG and even rival club Manchester city.
It is very difficult for Newcastle to be able to compete and beat the club and reach the semifinals, unless Newcastle can bring in a star player with very strong talent
We should not jump to conclusions because there have been many improbable things happen in the world of football. Never underestimate average less valuable clubs; they are capable of winning any title as long as they put in the effort and have luck at their disposal. Newcastle are a competitive club in the English Premier League, despite the fact that no one recognized the club until last season, when the appointment of a new manager, Eddie Howe, changed everything completely about the club. Checking their statistics, they have improved significantly, and I'm looking forward to watching the magpies in the Champions League next season.
Newcastle have not been in the Champions League for a long time, this season they come because of their performance last season, I don't think they will immediately compete in the UCL because this is an elite competition, even Man city, Real Madrid and other big teams are still difficult to face this competition, so I don't think Newcastle will go further, but by entering the UCL means they have shown quality.
Just enjoy their journey in the UCL until where this team will go, I wonder in the group stage draw sometimes here also if they are put together in another big group it will be difficult especially if there are Bayern, Madrid, Man City or Barcelona.
