I don't know about the rest of you, but when my club gets a new player my first instinct is to fire up the ole YouTube machine and watch endless highlight videos of the new signing. So, here's the best video would could find of Janssen that best represents what he brings to the club. A video of every goal he scored last season:
There are a wide variety of different goals in this highlight reel. The Eredivisie is known for being a high scoring league that sometimes inflates attacker's numbers, but some of the goals he scored would be impressive in any league in the world. He's a pure striker and should finally be the compliment that Harry Kane has needed for some time.
AZ Alkmaar and the Eredivisie have produced plenty of strikers in the past. Here's to hoping Janssen ends up more like Wilfried Bony and less like Jozy Altidore (*cries uncontrollably*).
