Look at the prices Liverpool got for the likes of Solanke, Ibe, Brewster etc, look at how much Watkins cost before kicking a top flight ball.
As much as Tammy has too many flaws to be a starter here he offers a guaranteed healthy goal tally that will be goldust further down the league. If punts like Brewster can command £24m then Tammy for £40m is more than a fair price.
