In today's world of modern football it isn't unusual for there to be several players at the top clubs earning in excess of six figures a week in wages.
Manchester United are no exception. Indeed, with the likes of Wayne Rooney and Paul Pogba pulling in some £300,000-per-week, a lot of fans think the Old Trafford club shouldn't be so generous.
But it hasn't always been that way. Way back in the days of legendary United boss Matt Busby first team players could only dream of earning a fraction of Rooney's weekly wage in their entire lifetime. A fact proven by a contract offer from United to one of their players back in 1965.
A letter, found by the grandson of former Red Devils goalkeeper Pat Dunne and posted to Reddit, has shown how things used to work over 50 years ago.
It shows the £35-per-week contract offer sent the way of the shot-stopper whilst letting him know that he could continue negotiations with "Mr. Busby" if he visited the iconic boss at Old Trafford.
The letter can be seen via this link, and reads:
"In accordance with Football League and Football Association Rules, I beg to advise you that the club desire to retain your services and wish to offer you a two year contract on the terms stated below with the option of a further two years as provided by the new agreements.
"Forms are available at this office, if you wish to discuss any matter with Mr. Busby he will be available any morning at the ground."
Even with inflation - £35 was worth around £640 back in 1965 - the offer wouldn't even be enough to entice an up and coming academy graduate in the modern game.
In the year before England won the World Cup, however, it was a more than appealing offer and Dunne duly signed up for two more years before being sold to Plymouth Argyle for £5,000.
In total, he made 45 appearances for United between 1964-67 and helped the team clinch the old First Division title in the year his 'bumper' new contract was signed.
The discovery of his contract offer is yet another example of why it is impossible to compare today's multi-million-pound football industry with previous generations.
£35-per-week would have been a big investment back in the '60s. Today, it wouldn't be enough to pay Pogba for more than a couple of minutes out on the pitch.
