Andre Onana is a goalkeeper who is still very young, doesn't have much experience, and can be said to be immature because he still has points of gaps and weaknesses when the opponent manages to get a score from a kick in the middle of the field and break through Andre Onana's defense. Hopefully, in next season's match, Andre Onana will perform better and focus so that it makes it difficult for opponents to score goals.
Andre Onana is 27 and I can’t call him young not to talk of very young. He has not been opportuned to play for bigger clubs in his career but he has some experience over the years, he won some trophies with ajax over the years and also he has participated in champions league couple of times which is the highest stage of experience before joining Manchester United. He is good but just has the problem of going out of his own 18 yard box whenever his team attacks and he loves to receive the ball and as a goalkeeper you are not supposed to receive so many balls because of costly mistakes around your goal area. I believe he will learn from yesterday’s match and reduce the way he go out and also I believe the coach will correct him of his mistakes and warn him to be cautious.
Newcastle can't be competitive for the Champions League much for now. Maybe they are one of the richest teams in Europe but they still can't make their squad one of the bests yet. It isn't an easy task to convince big names into their squad despite qualifying for the Champions League. They need to maintain consistency in the Premier League first.
Because the Champions League is not an easy league and they would need more experienced players to go far in the league and also maintain their performance from last season if they want to survive the group stage, they really lack the squad to perform wonderfully in it this season. Until they consistently qualify for the Champions League each season, it will be challenging to sign big-name players since everyone wants to be seen in the Champions League.
