Oh right, yeah of course. There are usually two or three players a year make the move to Football League clubs from the Isthmian and there are often Football League scouts sniffing around. Quite a few players in the league have played at at least a handful of games for League or Premier League clubs so the standard is good. I wouldn't be surprised to see Emenike go on to do well for us.
But he's over 6 foot so will have long legs to cope with such a large step. I would be worried if Roberts came from that league.
I think it's because as supporters and where the club is, we've accepted these are the kind of signings we make now. Good luck to him.
