Tactical flexibility key to survival, says Reg

Régis Le Bris has hinted that he could yet revert to a back four for Everton's visit to the Stadium of Light on Monday night.

Le Bris started with a back five for the first time in his Sunderland tenure against Chelsea last week, handing Lutsharel Geertruida his first start in the heart of defence.

The Black Cats fought back from an early goal to seal a famous win, but the head coach says it doesn't mean the switch is permanent. He pointed out that the team have been close to playing that shape within games, highlighting Granit Xhaka's habit of dropping into the back four.

"I don't know yet, we'll see," Le Bris said of his formation dilemma.
