Arsenal is still facing Liverpool , Manchester City and Newcastle. They are also playing against Chelsea, but I wouldn't say that that game is as hard as it once was when Chelsea was in shape. Manchester City is still within striking distance and Arsenal also has to play away against them. This can still go a lot of ways but I wonder whether Manchester United can be successful enough to play for the first in the end. That would be the icing on the cake for this season when it turns into a three-way fight.
Arsenal will beat Liverpool and Newcastle but Manchester City will always be a hard game for them. Newcastle have lost their form recently and will probably drop lower down in the league because of it and Liverpool have been very bad and are no match for the Arsenal attack. I expect Arsenal to beat Liverpool by a lot of goals.
