Wolves manager Mick McCarthy has revealed that he was left frustrated in his attempts to sign Liverpool full-back Paul Konchesky.
The defender, who had a turbulent time at Anfield following his summer move from Fulham, proved to be an unpopular figure during Roy Hodgson's reign and was shipped off on loan to Nottingham Forest.
McCarthy was in pursuit of the 29-year-old prior to the move, but found his efforts rebuffed due to a ruling that Konchesky could only go to a Championship club on an emergency loan.
The Irish boss was clearly annoyed by the ruling, citing that Konchesky was not the only player he found difficult to acquire and that the system of players only being registered to two clubs per season was flawed.
"I think the whole system is ridiculous," McCarthy told the Birmingham Mail.
"You think there's the whole Bosman thing they can go for nothing when they're out of contract and yet under contract they are restricted.
"If a manager doesn't want you, you can't go off and ply your trade somewhere else.
"We had a look at a number of things but some of them couldn't even get off the ground.
"We were looking at different players. But there's the thing that you can't go to three clubs.
"There's Paul Konchesky. I saw he wasn't going to be playing and thought about him but he can't come to three clubs in the Premier League.
"But he can go on an emergency loan to the Championship. I got told that even if we were interested in Konchesky we couldn't do anything.
"He has gone to Notts Forest and he can play there. There are some real contradictions in the whole transfer system.
"Just to have these two times of the year when they can change clubs. What is all that about?
"Why can't you have three clubs? Is that protecting them from agents getting fees or something? I have no idea.
"How frustrating is it if you are that player who can't go anywhere and the manager doesn't fancy you at the club you are at?
"We looked at Jonathan Woodgate but as it turns out he might be in the Tottenham squad tonight, which is great for him."
McCarthy also revealed that he never had any intention of selling any players on deadline day, despite agreeing to striker Sam Winnall joining Kilmarnock on loan, but it did not materialise due to the SPL club being undecided on Connor Sammon's future.
"Sam Winnall may have gone to Kilmarnock but that was held up by Conor Sammon (who moved to Wigan) as to whether it was going to happen or not," he added.
"I think someone was trying to ring me but my phone was switched off - we'd done our business!
"There was never a chance of anybody going out of the first-team squad and we weren't going to do anything on deadline day."
