Everton boss Ronald Koeman claims that "everyone loves" Romelu Lukaku after he scored a late brace against Hull City on Saturday.
Calvert-Lewin's maiden Premier League goal put the hosts ahead early on, though an injury to Morgan Schneiderlin resulted in a stuttering display from the Toffees.
Having rejected the most lucrative contract offer in Everton's history, worth a reported £140,000-per-week, Lukaku this week admitted the club's failure to compete for major trophies and attract top players was likely to convince him to leave.
Lukaku's comments angered Koeman, but the Dutchman knew only too well dropping the Premier League's top-scorer would amount to cutting off his nose to spite his face. United face Middlesbrough on Sunday.
His double on Saturday, with both goals in added time, may not have been the decisive factor in putting the Toffees level on points with fifth-placed Arsenal, but it at least showed his professionalism can not be called into question. I am not afraid because the player has two years left on his contract. It's up to the club to get the deal over the line'.
Keeping his composure impressively, he struck with a close-range finish after fellow youngster Tom Davies unhinged the Hull defence with a precise cross.
Marco Silva's side responded well to going behind, but any hopes of a Hull comeback were all-but ended when Tom Huddlestone was dismissed - harshly so - for a lunge on Idrissa Gueye midway through the second half.
With not even a hint of a boo every time he touched the ball, his stature in the game rose as the minutes ticked by and he set up Enner Valencia with a peach of a return pass to make the score 2-0.
