JAMES McCARTHY will join Everton today if Marouane Fellaini's transfer to Manchester United goes through and the Toffees meet Wigan's £14m asking price.
The 22-year-old has not yet joined up with the Ireland squad in Portmarnock ahead of the World Cup qualifiers against Sweden and Austria after Giovanni Trapattoni gave him permission to stay in England until tomorrow to resolve his club situation.
The 76-year-old was speaking during a promotional visit to the K Club with the FA Cup, and he actually took a phonecall from Everton boss Roberto Martinez while speaking to journalists.
"Roberto is chasing James," said Whelan. "If Everton sell Fellaini, they're going to come in again for our boy.
"It depends whether Fellaini goes today. I have heard that he's definitely going.
"If Fellaini goes, Everton are going to get their £30m or whatever. Roberto knows what James is valued at so they've got to come back in with the right amount. You've got to be talking £14m or maybe a little more."
Whelan added: "I would never stop a footballer going up to a bigger club, or to the Premier League. I know what it's like if you stop a footballer going to the club he wants to go to; you never get the same response or loyalty out of him ever again if you stand in his way."
It was a good weekend for Trapattoni, with all his main players coming through their club commitments unscathed.
Stephen Kelly has withdrawn from the squad for Friday's match against Sweden after his wife, Helga, went into labour with their first child. Trapattoni gave the defender permission to stay at home but may recall him for the trip to Austria.
Norwich winger Anthony Pilkington, who underlined his commitment to the cause by posting his Irish passport and boarding pass on his Twitter account, has met up with the group for the first time after injury prevented him from accepting previous call-ups.
