Looking at the pictures the club tweeted we have Harvey Lintott on trial, a young RB / RW who was released by Gillingham last season.
I'm not questioning your knowledge but I haven't seen him myself. I've seen a couple of "new lads" who look similar to the lad you mention, one is Jack Connor (striker) who recently signed a pro deal and the other is Ryan Nolan our centre half who was at Kidderminster on loan at the end of last season. Like I say you could be right and I could be wrong. Is it possible to describe the picture in any way?
