He's scored four goals, yes, but two were penalties and one was literally the opposition keeper booting it off of him.
Let's not act like he's in blistering goalscoring form.
His general play over the last month and a half has been excellent. Doing what he does best - dominating in the air, bothering defenders, holding up play. Some lucky goals, some penalties, an assist in the last match. But his profile offers a lot more to a manager than say Ivan Toney when it comes to 3rd pick behind Kane and Watkins.
For the Euros it should be Solanke, but afterwards - no reason for him not to target callups.
