The club is well aware of media reports and speculation linking Omar Bogle with a move away from Blundell Park
The 23-year-old frontman, who currently tops the scoring charts with 16 goals, is bound to attract the attention from other clubs, but the Mariners are keen to hang onto the highly rated player.
Speaking to gtfc.co.uk, Town director John Fenty said: "We are wanting to do well and we need to keep our best players."
"Omar is not for sale and is contracted to the club until at least the summer of 2018."
