Everton boss Sean Dyche has revealed that his side are worried about the fitness of Dominic Calvert-Lewin.

The centre-forward played an hour of their 1-0 win over Arsenal in the Premier League on Saturday.

However, he came off and is now a doubt for their next game against Liverpool.

Post-game, speaking with reporters, Dyche said: “We just had a chat with him to see where he is at, see how he is feeling about things.

“His body is getting stronger. He's niggled his hamstring which was a risk and reward situation because he's been a bit up and down with that.

“We said just give us a chance to work with you and you will get stronger. We talked about the basic principles, we showed him the goal reels and said 'look where you are where you have scored goals.'

“We showed him the goal map and said to him 'look where you are: get between the sticks.' Sometimes you can strip things out of the game, you can do all the analytics, but sometimes it is just a case of being in the right place, it gives you a better chance to score.

“So sometimes you have to strip all of it back and go right you work hard, work from the front, and when we get the ball you get between the posts, and you drive in there. Don't just stand there, drive in there and I thought he did that (against Arsenal)."
