The problem with signing a free agent is match fitness, unless they've been playing for a club who have suddenly released them, they've obviously not been playing games, they can be physically in great shape but it's a huge difference. We're now in February, if we brought a free agent in today, by the time they're match fit the season will be pretty much over.
Jack Wilshire is a quality footballer, but with his injury record I'm not surprised he's still without a club, he will probably end up abroad or league one. Look at Kevin Stewart as an example, he left Hull because he wanted to stay in the Championship, his injury record put clubs off so he ended up dropping down to league one to sign for us. We were willing to take the risk as we got a Championship level player in league one, unfortunately in hindsight it was madness to give him a new contract in the summer.
