Would a shock call up for ex-Sheffield United striker Dominic Calvert-Lewin cost Everton more money?

Farhad Moshiri owner of Everton looks on prior to the Premier League match between Everton and Stoke City at Goodison Park on August 12, 2017 in Liverpool, England.

Everton signed the 20-year-old from Sheffield United in August 2016.

Everton's Dominic Calvert-Lewin is expected to join the England senior squad for Tuesday's friendly against Brazil, the Sheffield Star reports.

The Sheffield United product has enjoyed a remarkable 15 months, in which he has gone from being on the periphery of the Blades' League One squad to becoming a Premier League regular with Everton.

And the prospect of another landmark moment for Calvert-Lewin, who has already fired England's Under-20s to World Cup glory and won his first caps for the Three Lions' Under-21s this year, has got some Sheffield United fans seeing pound signs.

But are the Blades actually in line for a windfall if the 20-year-old makes his senior debut next week? According to a Sheffield Star report from September 2016, they should have already received the full £1.4 million owed by Everton.

It reads: "The Star understands that United can expect to receive a guaranteed £1 million from Everton over the course of the teenager’s contract... United will receive the remaining £400,000 if Calvert-Lewin wins an England under-21 cap or makes a senior appearance for Ronald Koeman’s side [both of which have now been ticked off]."

But even though Everton's debts appear to be settled for the time being, United are said to be due a percentage of any future Calvert-Lewin sale.

It is claimed the Sheffielder could be joined by Liverpool's Dominic Solanke and Leicester City's Demarai Gray in Gareth Southgate's updated squad.
