Don't be (or at least display) being total fucking imbecile.
You know very well that I and no one else knows that right now.
All I know is that he is soon 27 yo striker who has had ONE good season in EPL and who has never ever in his career stood out by any ability whenever I've watched his team play. But as someone correctly pointed out, there have been loads of such strikers in past 10 years who have one good season and then totally faded. Everything considered I find that likelyhood of Solanke being next in that line is very significant.
Your logic is that because other strikers had one good season and failed that Solanke will do the same. Cool.
