I felt Janssen had a good game, he worked hard and there is a discussion on here about whether we are creative enough as a team, hence the number of chances were low.
However, I thought he should have done better with that header in the first half. He reminds me, not of Soldado, who was a technically superior player, but of Gary Doherty. His hold play is strong, lacks pace, can tackle and defend.
But Doherty would have finished that chance in the air.
I think he would be better with another striker who can run beyond him. When he held the ball up or won it wide, he looked up to deliver into the box, but there was no one there. If another striker was in the box, he would look better. Kane might well adapt to this. In which case we might actually look more threatening.
