19 year old striker Ahkeem Rose agreed to join the Mariners on an 18-month contract.
The Jamaican front man, impressed youth coach Neil Woods after a short trial last season.
Speaking to gtfc.co.uk, Neil said: " He's a very quick striker, scores goals, and he's got a fantastic work ethic.
"He needs to get better, holding the ball up in tight areas, but he's something from the 21's downwards that we don't really have in our system.
"We had him in at Walsall, we had him all pre-season, and we really liked him. Unfortunately we had just committed to bringing in three first year strikers. So he wasn't the right fit at the right time at Walsall. Everybody liked him as a person, everybody liked him as a player."
