Seems highly likely / almost certain that Waters will be on his way out. Either on loan or on a free.

I strongly doubt that any of our other strikers from last season will be leaving. So, even assuming that Drummond has been signed primarily as a winger, that would only leave a single striker position in the squad free. Tshimanga has been strongly rumoured to be on his way in. I suspect that’s likely to be it, so far as strikers are concerned.
