This scenario hits differently to Liverpool players and fans if the Arsenal and Man City match gets drawn on next week's Sunday fixture. The top 3 teams are in a race for the EPL title and every match for every team is very important a single draw benefits other teams to make sure to secure the Top position in the EPL table.
Arsenal and Manchester City will continue to try to win with any opponent now, especially if the opponent is a team that is blocking them in the League table in first and second place. So Arsenal and Manchester City will try not to get a draw in the next match in the Premier League because apart from being detrimental to both of them, it can also benefit Liverpool if Liverpool can win at home in the next match. So the remaining games of the season will always be important for these three teams now.
Anyway, even if, for example, the match between Manchester City v Arsenal does not end in a draw, that means there is a winner in this match. So yes, and for example Manchester City wins but in reality Liverpool will still return to the top of the standings if Liverpool also manages to win at home against Brighton. Also, if for example Arsenal wins, but in fact Arsenal and Liverpool points will still be the same, but indeed, this scenario is only if Liverpool also manages to win against Brighton. Therefore, I personally am still confident that the fight for the title between these three teams will continue even though indeed, in the next match Manchester City plays against Arsenal, and whatever results happen in this match will still make these three teams still will on track to compete for the title.
