Chelsea only won 1 of their last 6 league games with a poor form. Fortunately, the top teams have been underwhelming lately, so they are still the 4th team in the rankings.
On the other hand, Everton’s recent form is great, but they have been weaker on away soil with only 1 win out of 4 away games lately. Moreover, the Blues were the superior side in previous home games against the Toffees.
Therefore the hosts should be supported.
