Embarrassed 3-0 at the Stadium of Light four months ago, Everton returned to thump Sunderland by the same score on Monday night and underline Ronald Koeman's fine start with a third league win in succession.
A poor first half gave way to an excellent second as Romelu Lukaku emphatically ended his goal drought with an 11-minute hat trick. This was the clinical finishing lacking in wins against West Brom and Stoke.
Positives
It was not so long ago that a gust of wind seemed enough to unsettle the Everton defence. Even with the Koeman era in its infancy, those days appear over.
