Chelsea played a very good game; they dominated the match completely, they proved to be the best team in the match, their players showed quality, and they won the match at the end, which is exactly as expected by so many people, including Chelsea fans, because it will not be good if Chelsea is eliminated in the FA Cup. Chelsea needs to look serious in the FA Cup; they need to win the FA Cup to do the same thing as Manchester United did last season so that their fans will have relief from all the players they signed for huge amounts of money, so that the team management will feel relief and the team will be able to sign more players by avoiding financial fair play.
Yes, Chelsea won the match with a landslide victory against a very weak team but yet struggled in the first half. If Chelsea play like this against any present top six teams in the EPL, the game would have been over in first half for Chelsea. Unless drastic improvement happens, I still don't see Chelsea in Europe competition next season.
If there is anything I hate about Chelsea this season, it is their sluggish style of play. You don't have to be romancing ball before you score. You need to take any available chance, take the ball to opposition box, give a killer pass and take the shot when necessary. All these useless passes without vision is just not the way forward at the moment. Fortunately, they advanced to next round.
