I think the match was quite tough for PSG because they had to travel to St James Park stadium in their second match in the Champions League. Newcastle United is not a weak team because they were able to stop AC Milan in the first match to get full points, so PSG looks like they will have difficulty getting 3 points in this match.
Currently, Mbappe is injured and it looks like this will affect PSG performance in this match. If Mbappe has not recovered completely before this match starts then this could be a big loss for PSG. I think Newcastle United is slowly showing good performance in their game this season. I hope Newcastle United can win this match because if they succeed, the competition in Group F will definitely be even more exciting.
PSG has an outstanding attack and midfield. And the best fullback in the world, and they have one of the best shot-stopping goalies in the world. They have a manager who has won the treble before at Barcelona, of course their experience in the UCL League has been tested. So I think it's impossible for Newcastle to beat them.
Indeed, so far Newcastle United has developed and is better than last season. If they stop doing more in the game against PSG later, they might start doing better. Because there will still be a reality check because the UCL League is tactically at another level. Even though Newcastle United managed to win big in the EPL league and beat Man City in the Carabao Cup, the UCL league has a much different atmosphere.
