Royals boss Jaap Stam has confirmed interest in taking Wilson on-loan.
Speaking of Wilson, he said: "I know about it and we already spoke about him in June. But at the moment there is nothing in that.
"I'm not going to name names, but we are looking at players. We're looking at the team, how we are set up and asking whether we need to do anything and bring in players in certain areas.
"So yes, we are looking at certain players who can improve the team and add extra quality to the squad. But that's not going to be easy because clubs don't want to sell their best players in January.
"Even now we are working hard and making contact, but that's up to me. I'm only saying what I would like to see happen in terms of what we need to do."
