Arsenal fans are really disappointed, because Arsenal could not perform well in 3 consecutive matches. Arsenal has drawn 2 matches and lost 1 match in the last 3 matches, such a performance was not expected. Arsenal lost, which led to Liverpool progressing further. Liverpool are 15 points ahead of Arsenal, Arsenal have 55 points and Liverpool have 70 points. If Liverpool do well in the next few games, no team can stop Liverpool from becoming champions. Now it may be difficult for Arsenal to stay in the number two position, because Nottm Forest is in the third position in the points table with 51 points, so Arsenal will have to perform well in the next matches and win the match to get full points.
They performed very well in the champions league, but unfortunately when they returned to the EPL, the results they got were less than satisfactory. They found it very difficult to win. While for the next match it might be more difficult because they will face Chelsea and Fulham, and if Mikel Arteta's team doesn't get a win again, they will not only be further away from Liverpool, but as you said that their position as runner-up in the standings will also be threatened. Because considering that at this time the points difference with Nottingham Forest is quite thin, which is only 4 points.
Nottingham Forest became a big surprise this season, because they managed to compete tightly at the top of the standings, something that other teams could not do, such as Manchester United, who even though they had made many changes to their team, but now their position is the same
Arsenal had lost their chances of competing with Liverpool for the premier league title when they lost at home to West Ham that is an incredible result since then the team had became a shadow of former self except in UCL where the club is on verge of qualifying for the quarterfinals, it's a pity Arsenal drew Man Utd and could have even lost that match of not for Raya brilliant saves, this is a match they dominated and took most of the possessions yet couldn't find the back of the net due to lack of a competent striker now the team would end up as a runner up in three consecutive seasons absolutely squandered their chances of winning due to lack of depth in their squad.
