Bergwijn is moving to Spurs for a fee of around €30m.
He told De Telegraaf: "The Premier League, that is the highest thing achievable for every football player.
"It also feels like the right time to take this step.
“Of course it will take some getting used to, but it will be alright.
"I believe in myself and I really know that I am not there yet. Of course I have played many matches in the Eredivisie. Yet England is a bit different, but I know what I can do:
“I have always looked up to a top coach like (Jose) Mourinho. And now I'm going to play for him. It's great to be there."
