As we mentioned earlier, Loaded’s Jeff Maysh is joining the blog team here at Umbro to give the inside track on all the world of football shirts. Jeff’s a big collector of shirts, and knows his football – despite being a Spurs fan. Here’s his blog for us, where he looks at the detail that goes into one of David Beckham’s England shirts.

‘Only Posh Spice gets to see what’s inside Beckham’s Umbro shirt, (although most of Earth’s female population would gnaw off an arm for the chance). But there are others who dream of getting their hands on Beckham’s ‘used and dirties’: They are football memorabilia collectors.

And this week, some mega-rare England shirts were seen floating around cyberspace, and have raised the blood-pressure of such collectors of ‘match-worn’ garments. These shots are of some of David Beckham’s shirts from the Brazil match in Qatar on November 14th and various other Internationals. Becks pulled out of the Brazil tie, so his kit went unused, but for the first time you can see the detail that goes into Goldenballs’ real match shirts.

The match details are lovingly embroidered to the chest, (like the example above from a player’s Slovakia shirt) along with the year of the match. The shirt has been tailored specifically for David’s fit, and we can reveal here that Mr Beckham is a ’40 regular’. David’s Umbro logo is a little bit ‘different’ too, so it stands out on the on telly when he’s hitting those ‘Hollywood’ balls. Oh, and the button inside even reads: ‘Player’s Bespoke.’ Nice touch.

Shirt collectors know that kit worn by Beckham fetches the most money: A pair of the former Manchester United star’s boots once sold at London auction house Christies for £13,800. But the most expensive football shirt ever to go under the hammer, was Pele’s 1970 World Cup Final shirt. It sold in 2002 at Sotheby’s for a staggering £157,750. So if Beckham wants to improve the worth of his custom made Umbro shirts, he knows what he has to do: Lift the World Cup in 2012.’
