Daniel James’ price tag has soared to £30million just two months after Leeds United came so close to signing him for £10million, according to former Wales international John Hartson.

The Swansea City winger’s reputation has been enhanced by a series of sparkling performances for club and country in recent weeks, culminating in his first international goal in Wales’ win over Slovakia on Sunday.

Former Wales international Hartson has been impressed at the development of James, who underwent a Leeds medical on deadline day in January before the transfer collapsed at the eleventh hour.

“He’s got a bright future,” Hartson told talkSPORT. “He scored a goal in his second cap where he was starting on the left-hand side. He has ridiculous pace and played well against Manchester City in the FA Cup.

“He was almost out of the door and was up at Leeds signing for £10million and he brought him back.

“I think that will treble now with the market the way it is.”

Football Insider verdict:

Is Hartson talking telephone numbers? Or, is this a realistic price tag for a player who Leeds so nearly signed for an initial £1.5million loan fee that would have been converted for a further £8.5million into a permanent transfer in the summer window if they are promoted? Well, Hartson is right on one count: the market is showing no signs of slowing down. Much depends on how James fares over the final eight matches of the Championship season. He made a big impact in Swansea’s FA Cup run, scoring that wonder goal against Brentford and causing alarm to Manchester City’s defence with his blistering pace. James’ actual achievements so far don’t amount to all that much, but he is bursting with potential and starting to ally better decision-making and end product to his jawdropping speed. Perhaps £15million might be a more realistic price tag for James at this point. Even amid Premier League club interest, it’s hard to see anyone paying much more than that.
