We didn't buy the finished product in Janssen, we knew that beforehand. It was always going to take time. He comes from a subtop team in the Eredivisie in AZ, and even there it took a while before he started scoring regularly. And he only played for AZ for one season, before that he was at Almere City for two years, a mediocre team from the Dutch second division (that's probably somewhere between league 1 and 2 in terms of quality). As I said, the step up is huge, he'll need time. Many of our players needed one or even two years to show their qualities for us, and they often came from bigger teams/leagues.
