While Haaland scored the opening goal, he was unable to provide a result for his side as Brighton fought back to steal the three points, and Van Hecke's Netherlands team-mates were looking for the Norwegian forward in his pockets days later.
"A few guys at Oranje looked in my pocket on Monday night as a joke, to see if Erling Haaland was supposedly still in it," he added. "But I have to be critical. We won against City, but Haaland did score, so he wasn't completely in my pocket. It went really well on Saturday. I played well, and when you win 2-1 against Manchester City, you automatically get a lot of compliments."
