Hendo has been on fire since his arrival at the County Ground. At time of writing, he's banged in four goals in four games for the Robins - and manager Andy King has made it crystal clear that he wants to sign him.
However, Gillingham had huge problems in front of goal last season and although Iwan Roberts and Darren Byfield are doing the business so far, we need striking cover, particularly for Roberts. Pat Agyemang is proving inconsistent, while Mama Sidibe has proved a flop in front of goal so far in his Gills career, so we might want to keep Henderson.
Put yourself in the shoes of the chairman and the manager. What would YOU do?
Would you sell Henderson to Swindon, making a tidy profit along the way?
Or would you offer to extend his loan spell at the County Ground?
Or would you bring him back to Priestfield and put him in the squad for the upcoming games?
