Everton manager Frank Lampard has confirmed striker Dominic Calvert-Lewin will miss Saturday’s Premier League opener against Chelsea after sustaining a knee injury in training.

The England international is currently being assessed by the Club’s medical team and will continue treatment at Finch Farm.

Lampard said: “We are assessing Dom’s injury. No timeframe has been confirmed and we are pretty sure what level it is so we are hopeful it is not long-term.

“We’ll miss him for Chelsea. He was looking in great physical condition and was training really well. It was a freak injury in training, which does happen. It’s a shame but we have to find the solutions to keep ourselves strong without Dominic before he returns.”
