A standard adult Blues shirt costs £53, according to the BBC research.

The average UK employee earns £11.54 an hour according to the government's latest figures.

It would therefore take the average UK worker 4.6 hours in order to get enough money together to buy the shirt - and that's before you even think about income tax.

Spare a thought for Manchester United fans though who face having to work over five hours in order to afford one of their club's £60 shirts.

Premier League rivals Arsenal, Manchester City and Tottenham each charge £55 for their adult shirt. Someone earning the UK average salary would have to work 4.8 hours in order to be able to afford any of those sides' shirts.

The cheapest shirts of any side in England's top four divisions is Newport's.

An adult shirt for the Welsh side costs £37.50, which would take the average worker 3.3 hours to earn.
