Lukaku calls for man utd arrogance against barcelona in return leg

I think there may be some misinformation here!

Romelu Lukaku, the Belgian striker, has never called for Manchester United to show arrogance against Barcelona in the return leg of a match. In fact, Manchester United have not even played Barcelona in a Champions League match recently.

It's possible that you may be thinking of a different player or a different match. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you further!
