Yes,If Liverpool loses like in the upcoming match against Nottingham Forest then Pep's troops will be lucky to have a big chance of becoming English Premier League champions.
But I think Arsenal fans will support them even if they don't win this season, but of course Arteta will definitely work hard to train his men and prepare their physical condition and other things so that Arsenal's performance will be good when they face Sheff utd.
The three teams are currently in a crucial phase to be able to maintain their position at the top of the standings, because if they slip up even once then it is certain that another team will take their position, currently Liverpool, Manchester City and Arsenal are on the championship track and they have to be really able to handle every pressure to maintain consistency in every remaining match this season to guard the opportunity to become champions, as far as we can see Liverpool and Manchester City are the strongest candidates compared to Arsenal in the race for champions this season, it is not without reason that many people still doubt Arsenal to win because from previous experience, especially last season, we can see that at the end of the season they often have problems.
The Nottingham vs Liverpool match will certainly be a difficult match for both teams, Statistically Liverpool is superior to Nottingham, but I think we also can't underestimate Nottingham which might make Liverpool difficult in the match, Nottingham will face Liverpool with quite poor capital. after 3 defeats, 1 win and 1 draw from 5 league matches, while Liverpool are actually quite confident after getting 5 consecutive wins so far after their last defeat in week 23 to Arsenal, I think even though it will be difficult to face nottingham at home, but with the positive performance so far means that Liverpool will be can to overcome Nottingham resistance in that the match.
