I was asking myself that question when I was typing it. In a squad are you looking for a group of 5 forwards whose style complement each other, or are you aiming just to have an option to bring on a potential goalscorer?
I like the fact that Long is quick and runs at people. I also like Clinton's game. On balance I'd prefer Clinton in the squad but I'm not that fussed. I think Long needs to justify his selection with some good club form though. Potential isn't enough to warrant being picked all the time.
