Everton have shown the most interest in the midfielder so far during the summer as former Wigan manager Roberto Martinez wants to bring in another one of his old players.
Now, however, Newcastle manager Alan Pardew looks to strengthen other parts of his team as a deal to sign striker Bafetimbi Gomis could soon be completed.
Wigan have set a price tag of £20 million for the 22-year-old but Everton and Newcastle are confident they can get him a lot cheaper.
McCarthy shone last season even though Wigan ended up being relegated. Now the midfielder could head back to play in the Premier League if either Everton or Newcastle can make a good enough offer.
