The 21-year-old laid on seven assists in 22 Eredivisie appearances last season and his impressive performances have led to rumours that La Liga champions Barca are considering a move for the Netherlands Under-21 international.

"The talks about a possible transfer are still going on. I see all the newsflashes, everybody tells me stuff," he told Voetbal International.
"At first I thought it was kind of funny, but after a while I was thinking 'does this ever stop?' But besides all that, my summer was quite normal."
