Young at heart Newcastle United manager Bobby Robson is to star in a new TV advert - on roller skates.

The 68-year-old ex-England boss will be seen gliding along the streets while he shops, and mocking his ageing years in the ad for Barclaycard.

It is being seen as a kickback at Robson's critics who say he is too old for the job.

The ad will be shown when the football season kicks off next month, but the credit card company is refusing to reveal any more details until then.

The new series of adverts has a football theme and also stars Have I Got News For You host Angus Deayton.

In April, it was announced Barclaycard had agreed to pay £48m in a three-year sponsorship deal with the Premier League which sees them take over from Carling.

Other adverts in the soccer series will feature Manchester United star Roy Keane tackling Angus Deayton over a prawn sandwich.

Last year, Keane famously attacked the posh Old Trafford fans who spend more time munching prawn sarnies than watching the football.

Another ad features England goalie David Seaman buying hair products on his credit card.
