AZ Alkmaar director of football Max Huiberts is confident Vincent Janssen will prove his class at Tottenham.

Mauricio Pochettino's side eventually brought the Netherlands international to White Hart Lane in a deal that could be worth up to £20 million.

"Afterwards I thought: 'wow, nice, we have done well'. I was relieved that it was completed well. The buyers, Vincent Janssen, and we were very satisfied," Huiberts told AZ Spreekt.

"But I also understand the fans who think we have lost a very good player. That just happens, we have to deal with that in the Dutch league."

He added: "It was said that it was ridiculous that we asked more than 10 million for Vincent because he plays for AZ.

"But then I think why? He is the top scorer in the Netherlands and the number one striker of Oranje. I am sure that he will adapt quickly to the level of the Premier League."
