Arsenal's team is very stable. The bonding between the players is very strong. And because of this, Arsenal's performance is good against Renowned teams as well. I don't think home and away matches will have a big impact on Arsenal's performance. As Arsenal aims to win the title. So they have to play well and win every match. If they don't win any match they will be relegated. Now every match has become a do-or-die match for Arsenal.
They have stable good performance in this season and they always have star players who can save them or bring them to winnings. In addition, if you look at their winter transfer, it's a great success with Trossard who moved to Arsenal from Brighton. He is only an alternative for Arsenal after they lost Mudryk to Chelsea and we saw how he played so well in Arsenal.
I think many factors tend to support Arsenal in this season and likely all those factors together with Arsenal efforts will lead them to a crown for champions.
Liverpool's performance has been the most erratic in the Premier League this season. They scored 7 goals against Manchester United, and even Liverpool scored 9 goals against Bournemouth. Again they were defeated by this Bournemouth team. So it becomes impossible to make predictions about the performance of this team.
At least Liverpool are coming back and they still have chance to participate in top four but not all problems were solved. They must keep improving themselves in this season as well as doing many thingsin the summer to build up a stronger and less vulnerable to injuries in a next season.
Their defeat by Bournemouth can be considered as unlucky accident and they actually did not play too bad in the match.
