Everton are edging closer to signing Sporting Lisbon’s teenage striker Youssef Chermiti for an initial £12 million.

The 19-year-old only broke into Sporting’s first team last season, scoring three goals in 16 appearances, but he is seen as a potential answer to a chronic shortage upfront.

Sporting want 20 per cent of any future transfer fee. Everton want that to be 10 per cent. Once a compromise is reached, Everton can press ahead with agreeing personal terms and arranging a medical.

Chermiti has been at Sporting since he was 16 and is a Portugal Under-19 international.

Everton coach Sean Dyche has already signed Arnaut Danjuma and Ashley Young this summer. He wants more to ensure this campaign is not similar to the past two, when Everton narrowly avoided the drop into the Championship.

His need for firepower is obvious. Dominic Calvert-Lewin is a class player but has suffered numerous injuries over the past two seasons. Last season he scored just twice. Neal Maupay, signed from Brighton a year ago, has been unable to show he has the capacity to score regularly at Goodison. He has managed just one goal in his past 40 league and cup appearances.

Over their 38 Premier League games last season, Everton scored 34 goals.

Those kinds of statistics are unsustainable if Dyche is to avoid another fight against relegation and Calvert-Lewin was a notable absentee again during Everton’s pre-season friendly win at Stoke City on Saturday.

Dyche could not say when the England forward will be fully fit.

“He’s going well. He trained with us last week and is still crossing over between training and getting the extra fitness work he needs in, said Dyche.

“We’re taking it a day at a time because, as everyone knows, he’s had a tough period of it. So it’s making sure we’re not overloading him and he’s well in himself.”
