'How much would Roy Keane be worth if he was playing today?'
It's the sort of question that is often posed by football fans when discussing the modern transfer market - and now the Republic of Ireland assistant manager has got involved!
International week means the media get a chance to catch up with Keane and, as usual, he has proved well worth a listen.

And, having played with some of the best players in recent history, Keane was asked to put a figure on how much they might be worth were they at their peak right now.
Keane thinks forward Ruud van Nistelrooy and wide man David Beckham would both fetch a cool £1bn, while the great Ryan Giggs would go for double that.
But how much does Keane think he would be worth himself? Click on the video above to find out!
