As he was out of contract in the summer, other clubs were able to talk to him and possibly sign him on a pre-contract. I'm sure they're will have been clubs sniffing around but he obviously didn't commit to any of them. I can't see why another club, who had the option to sign him for nothing, would now want to pay a substantial fee for him.
It may be the case that a club who has not shown any interest so far might want to explore the possibility of signing him, particularly if he maintains his scoring rate, but I think it unlikely.
