Manchester City are now said to be preparing a bid for the Rams defender. City know they will have a fight on their hands as Derby try to hold on to the talented youngster as Liverpool have expressed their interest in the player.
Liverpool are said to be preparing a bid at the end of the season but Keegan is now expected to try an attempt to land Riggott before May.
This may or may not be good news for the Rams, as an auction between the two teams will undoubtably push up the price of Riggott, who is expected to command a price around £7million at the moment.
However with a new team boss imminent at Pride Park it now remains to be seen if the new man sees Riggott as expendable or wants to cash in on the England Under 21 International.
