Southampton 3-0 Everton: Roberto Martinez on defence

Everton manager Roberto Martinez says his side "must defend better" after their 3-0 away defeat to Southampton.

An own-goal from Romelu Lukaku gave the home side the lead and Graziano Pelle scored the second from close range, before Maya Yoshida headed in to seal the win for the Saints.

The Toffees have now gone seven games without a clean sheet away from home.
