Promoted Norwich City have upped the ante for Leeds United's Robert Snodgrass to £5million.
The Canaries had a previous offer of £3.5m rejected by the Whites but they are so keen on the Scottish winger that they will return with a stronger bid.
Leeds CEO Shaun Harvey insisted that the club would get due compensation for any player to depart Elland Road this summer.
"Any player leaving will only do so in those circumstances that we believe represents the best interests of the club and has the full support of Simon Grayson," he said.
