FC Twente coach Steve McClaren explained why Luuk De Jong chose Borussia Monchengladbach over a move to Newcastle United.
McClaren, who's in his second spell at FC Twente believed the lure of Champions League football over Europa League football was the biggest reason.
"Luuk is the smart one, his brain comes in different ways. He came to me and asked the opinion of me, I told him to go to the heart and ask it for its desire. Luuk came back to the reality and realised the dream of Champions League football. I told him the Newcastle is a good team, but the team who only play against team from the Israel, and the Bulgaria. Luuk laughed and I laughed the mouth, we drank the wine and ate the cheese, and together got the conclusion it merited."
