Not sure why people think Janssen is the problem, he starts, holds the ball up from 2 defenders then lays it off to Eriksen/Lamela/Onomah etc who do nothing with it.
We have a player who can bully any defender yet have no runners playing off him, Liverpool would have a mountain of goals with Janssen up top laying the ball off to Mane and Couthino 25 yards from goal.
As I keep saying Kane or Janssen are not the problem, the problem is in our AM's who offer little to no threat (Son excepted) despite the donkey work done by our striker/s.
If you want Janssen to get in the box more and shoot then our other attacking players need to raise their game and do more work further forward in support. Janssen has come from another league, is not yet fit enough and is still in the adaption phase yet his actual play is better than many of our longer term players and we are moaning.
We need a world class attacking midfielder far more than a replacement for Janssen.
