Everton boss Sean Dyche will use a combination of science and psychology to get the best out of Dominic Calvert-Lewin.

The center forward has barely contributed for the Toffees in the Premier League this season.

Dyche knows he needs Calvert-Lewin firing if they are to get enough wins to avoid relegation.

Asked about keeping DLC fit, he said: “You can imagine now we have got every stat you can virtually think of.

“We have got an insights team that has probably got as much depth as other clubs as well, even the ones who are onto every physical stat.

“We can do that, check his records, check where he was at when he was flying, where his body was at - but we speak to the player too, that's important.

“He is a human being and I believe in asking the player, going 'right, where are you at with it?' And usually when they feel right about it, it is a massive plus."
