Haven't a clue, was told he didn't like Southampton or Saints fans tho. Don't know if there's any truth in that.
Tbf to Phillips, we rejected him as a LB, when he was a kid. Then we got him back as a striker and many supporters didn't take to him, although I didn't have a problem, and finally he had emotional/partner problems while he was here. Not a memory of a great time in his life, I'd imagine.
