It was a very disappointing defeat, as it came against a team in a lower competition than them. If I'm asked if they deserve this defeat, then the answer is that they do, because in the game they are not so good and even the opponent can play better than them. Maybe the red card could be the reason for their defeat in this match, but still by chance when they were still playing with 11 players in the first half they did not show anything better.
West Ham must evaluate their defeat in this match, because if this continues it will be a threat that comes from within themselves when in the Premier League.
These are cup matches and it is obvious that West Ham did not have high hopes for these tournaments, the starting line-up for this game shows us this. Moes will concentrate all his efforts on the Premier League, this is obvious, and perhaps on the EL, as far as they have enough strength, but they do not have such a high-quality bench depth to try to qualitatively participate in more than two tournaments.
West Ham did not have a target in the FA Cup and therefore, West Ham did not play well in this match and West Ham preferred to be eliminated. It does not matter how weak the opponent West Ham faced in this match because yes, if basically West Ham does not have a target then a mediocre team like Bristol City will also be able to successfully beat West Ham.
Evidently, that in the first leg they also ended in a 1-1 draw and then, in this second leg West Ham played away and the result was worse because West Ham also did not have a good effort to be able to load goals in this match.
About the red card that West Ham players got in the second half, it has absolutely no impact on West Ham's defeat in this match. Because yes, once again West Ham has more to focus on in the Premier League as well as in the Europa League and therefore, West Ham is willing to miss out on the FA Cup this season.
