# 2 Strategy gone wrong
Ronald Koeman must have thought he could match Chelsea like-for-like by using three defenders and thereby contain them but he could not have been more wrong. Chelsea seems to have adapted very well to Conte’s tactics and from the way they started, the Dutchman should have tread on the side of caution and deployed his men in a way they were more accustomed to.
Everton’s defence was torn to shreds by the 20th minute as Hazard and Alonso scored within 70 seconds. The failure of his plan quickly prompted Koeman to replace Oviedo with Kevin Mirallas in the 36th minute but the damage had already been done. The defenders looked hapless before and after the change and were outplayed by the Blues all night.
