Williams said "I think that Joe is a player that has been flagged up even before I joined the club.
"He has been watched and I don't think that would be a surprise to anyone because he is a very high performer in the league at this level.
"He also has really good character references so he is a good guy, but I am not surprised that one or two people are talking about this.
"But at the moment, it's not our business and he is under contract at Solihull and until we are serious to make an actual approach for a player, it is not fair to talk about that.
"However, I think it is fair to talk about the quality of the player and the fact we know and appreciate how good he is, I am not going to deny that - I know for sure he is a player that has been analysed by the recruitment team here, so we will see."
