Percy goalkeeper story: want Henderson (obviously) also Sa (didn’t realise he’d played for Oly), because Hendo might not start the season. Horvath and Hennessey both injured as well, so Shelvey is currently only fit senior keeper.
Not likely any normal range injury, even a bad one, will do for a keeper. They don't run around, which is the normal problem with injury. They just wave their arms around.
Any player could get a terrible, career-ending injury at any moment. Signing one with a known injury doesn't increase the odds of that very much, I wouldn't think.
Teh rumourmillz have us signing 6 and selling 3 (specifically Freuler, Dennis and Shelvey). Can't see us shifting those and we shouldn't be bringing in 6 more unless they are young enough to not count against the squad.
