Wilson told Grosvenor Sport: "If Wrexham want to spend they can spend. You've of course got the regulatory processes that limit League One clubs and Birmingham, if they haven't exceeded it already, they'll be right up against the limits. I think Wrexham have behaved in a way that you would expect a team that's really trying to get that automatic promotion spot to have behaved. You end up with the opportunity cost of the acquisition. So if your nearest competitors aren't looking to sign players and you do, that two million transaction suddenly becomes a four, five, six million transaction because they haven't acquired. So you pull away from them. I think that's what we saw with Wrexham. It looks like smart business that should guarantee that promotion spot and it will be fascinating for us to get the accounts when they're due to see how close or how much they've exceeded the regulatory position and of course if they stay put then it causes them a much bigger problem later down the line."
