He's the one who was brilliant for the blades in their rise up the league's under wilder? If he's anywhere near that level still then get him in.
Apparently Blades fans loved Kieron Freeman, however that was a while ago now and he can't get in Pompey's team. So he's either declined significantly or his face doesn't fit there/needs a fresh start.
No Luke Freeman is the attacking mid. Kieron is the RWB they had for a while. It's definitely the one I thought. I did have to google then to double check though
