Holding midfielders and Left backs don't need to score often. That's not a legitimate complaint. For Townsend, yeah sure. Of course we need to buy. Every team has to add in the summer, doesn't mean we don't have a legitimate foundation to build on.
Think chavs exploited our weaker players today, Kane had 3 men on him every time he got the ball, someone like Depay or a player of his quality would give us the link we need in attack.
We are close to a very good first 11 and bentaleb could be world class in the years to come.
