"Our Chief Scout, Ben Strang, has watched Harry on several occasions for Charlton's U21s and has always been impressed.
He has all of the physical attributes that Richard was looking for in adding another defender to the squad. Harry is 6 foot 2 inches, left footed and quick. He is also able to play left side centre back or left back which will give some flexibility to our defensive options.
We have an excellent relationship with Charlton and therefore, despite interest from other clubs in our league for Harry, we were able to secure a loan deal until January. We would like to thank Charlton for all their help."

"Johnny is a very good footballer. He's a versatile, left footed player, with bags of energy and ability, who will add real competition in three positions.
"We have signed one of the best young players in the Conference and we look forward to him developing further through the philosophy and coaching environment that underpins our football operation."
