Arsenal on a bit of a league slump and Chelsea getting back to form would sugest a draw or Chelsea win, but then Chelsea have only beaten Arsene Wenger’s Arsenal twice in the Premier League, both under Jose Mourinho.
Glenn Hoddle 2 and Dave Webb 1 are the other Chelsea managers to beat Arsenal in the Premier League.
