It's almost impossible because Liverpool will probably never lose consecutive matches in their next one so at this stage I think they will never be knocked off the top of the Premier League. On the other hand it is now clear as water to us that Arsenal will never be able to top the EPL. Moreover according to the conversation you mentioned, Liverpool Football Club's sole goal is to win the EPL trophy. The truth is that, Liverpool Football Club may have given their best in everything before but due to some of their weak points they now have to constantly plan to fight differently to achieve the highest status. By the way Arsenal will definitely play well in the remaining games and they will face Fulham.
I am an Arsenal fan, but I believe what you said. It is obvious that we Arsenal have lost our chance of closing the gap between us and Liverpool since we lost to West Ham United and played a draw against Nottingham Forest, and Liverpool keep winning against Manchester City we were expecting them to drop points and so on.
It cannot be possible for Liverpool to lose two to three consecutive matches because they are eliminated in the Champions, and they also lost to Newcastle United in the Carabao Cup final, therefore, their only hope this season is winning the Premier League which many players that will leave the club after this season will want to achieve before leaving, therefore, I think the players will give their best in their remaining matches.
