Zaha at 7m is about the right valuation. He plays in a position we aren't blessed in, is young and home-grown. We need more of those players to replace the average Saylors and Raylors that we have.
If we continue with our work on Lascelles and Darlow and plan further ahead, we could replace the current eight HG player quota with:
Krul
Elliot Darlow
Dummett
Williamson
Saylor Lascelles
Raylor Bigirimana
Colback
Sammy Zaha
