When Mick McCarthy made Roger Johnson his third signing of 2011's summer window, it was a significant deal.

£7m was spent on the centre-back, which is worth £8.6m in today's money using the Bank of England's inflation calculator, and McCarthy had snapped up the man who he was believed to be a long-term admirer of after Birmingham and Johnson were relegated to the Championship.

However, one presumes that the ex-Wolves boss wouldn't have been in admiration of the defender for much longer.

In just his first season at Molineux, the Ashford-born man was involved in a number of unprofessional incidents.

Johnson took aim at supporters following a game against Newcastle after they cheered the substitution of Karl Henry, going as far as calling the Molineux faithful a "disgrace", "disgusting" and also stating that their behaviour "stinks".

He was entitled to think that, but those kind of comments won't endear him to fans too much.

It got even worse for Johnson.

Terry Connor - McCarthy's assistant who had taken the reins following the Irishman's sacking - noticed that the centre-back was under the influence of alcohol during a training session one Monday, where he was then fined two weeks wages and made to train with the development squad.

The Midlands-based club then suffered relegation in successive seasons to find themselves languishing in League One, where the club's chiefs decided to terminate Johnson's contract to get him off the payroll in 2015, putting an end to his miserable four-year stint at Wolves.

In total, he made 72 appearances for Wolves, which means he cost the club £97.2k per game when you divide his £7m transfer fee by his number of outings - he was a complete and utter waste of money.

61-year-old McCarthy has had many years in management, but one feels that he hasn't made too many signings who were as disastrous as Johnson was.
