I don't think there is anything worrying about it all for a club in our position. We had zero money in the budget, so took a guy on trial who said he was more interested in playing than getting a 'big' wage.
From what McCall said, he looked decent during his trials, but there were still some concerns - in particular, he didn't manage to score one goal in all his games. Also remember this guy had bounced around a few teams without making a breakthrough.
However, we could get him cheap, so we signed him on peanuts until the end of the season to see how he worked out. Once he got his chance in the first team and proved himself, the board made an exception and allowed McCall extra money to tie him up.
I would argue, therefore, we took a low risk approach that has paid dividends. Of course, every manager has stories about players that passed them by. I read this morning that Fergie missed out on Joe Hart for 100 grand.
