Interesting that both ourselves and West Ham have Chelsea and Arsenal in our next three matches. The difference is that our other match (Palace) is the first of our next three, but for West Ham it's the third (WBA). Chance for us to reclaim 4th on Boxing Day therefore.
If West Ham were to lose to both Chelsea and Arsenal, it might ultimately be a massive turning point for their season. After that WBA game, they could be losing Song, Sakho and Kouyaté to the ACON. Coping without their top scorer and the heart of the midfield would not be easy. That said, their squad does seem to have some depth to it - deeper than ours any way.
