Everton boss Sean Dyche will leave no mattress unturned in his bid to get striker Dominic Calvert-Lewin firing.
The Toffees coach knows that he needs his ace forward at his best if the club is to survive relegation.
Dyche will be without Calvert-Lewin for their next game, but hopes that the forward can be back for the run in.
Dyche stated: I've got to learn what his body will and won't take, which is what we are trying to do now.
We look at everything; what's his diet like, what's his lifestyle like, what car does he drive, what mattress does he use, how many hours does he sleep a night?
We're speaking to him, the medics, the sports scientists, looking at the stats, training programmes, distance covered, high speed running, how many kms in a week, That's learning about people."
