But, reporting the imminent move, The Herald made the mistake of using a picture grime star Stormzy rather than one of the Everton striker.
The caption underneath read: "New Manchester United signing Romelu Lukaku."
The picture in fact is from United's away kit launch from last May where he posed with David Beckham in London.
But Stormzy failed to see the comedy in such an error.
Stormzy is no stranger to the likeness between the two, however, and has referenced it in the past.
"I want to say a big thank you to all the people involved at Everton. "I want to thank the fans for their support throughout the four years we've spent together.
"You guys helped me through all my games and I can proudly say it was an honour to play in front of you. To the staff at the stadium and the training ground, thank you for making me feel at home from the first day I walked in.
"To my team-mates it was great to play with you guys. To the technical staff, thank you for helping me to become a better player. Working with you guys has been a pleasure and I'll take your advice throughout the rest of my career. Thank you Everton Football Club."
United jetted out to Califonia for their pre-season tour on Sunday with Lukaku set to be unveiled as their latest signing imminently.
