I think a win adds to the confidence of a team all the time, but when a team realizes that it can beat PSG with a groundbreaking 4-1 that gives an extra portion of confidence not only for the Champions League, but also for the Premier League. I am still missing some new big names on the team of Newcastle United as I thought they would use the transfer window and buy some stars. Maybe not superstars, but players that have proven themselves in a strong league over some period of time. These players are doing well, but it couldn't hurt them to have one or two players that also bring a different aura to the team. But maybe that is what they exactly not want and they think it could hurt the cohesion.
This victory is a sweet historical record for Newcastle. When returning to the Champions League stage and being able to win a match against a top team clearly had a tremendous impact on the team, the morale of the players increased. However, this brilliant record should not make Eddy Howe's troops forget themselves because they will continue to face tough tasks in the future.
Compared with the squads of other teams in the same group, Newcastle's strength means nothing. But I applaud their hard work and they really don't feel embarrassed playing in the Champions League. I hope Howe is able to maintain the consistency of his players so they can qualify for the knockout phase.
And if possible, I agree that Eddy Howe adds several experienced players so that conditions are more stable. Because if at any time an injury storm comes or is caused by suspension, the team's strength will not be easily shaken.
