MIDFIELDER James McCarthy has signed for Everton on the stroke of the transfer deadline while Latics also confirmed a late arrival.
Irish international McCarthy links up with former boss Roberto Martinez for a deal believed to be in the region of £15million.
Meanwhile, Wigan made an 11th hour move for 24-year-old Stoke City defender Ryan Shotton.
There has been much wrangling throughout the last 24 hours over McCarthy with Latics chairman Dave Whelan revealing twice he had rejected bids for the 22-year-old.
The first came on Sunday evening and was worth £7million up front with another £3million in add ons, which was way below Wigan’s valuation.
Everton’s second bid just hours before the window shut, although increased, still didn’t meet Latics’ demands and Whelan revealed that he thought the deal was off after Everton asked to pay in instalments over four years.
However, as the clock ticked down to 11pm, Everton stumped up the fee and the bid was accepted.
McCarthy joined Latics in 2009 from Scottish side Hamilton for £1.2million and scored seven goals for the club.
Latics did bring in Stoke defender Shotton with just two minutes to spare before the 11pm deadline.
He joins on a six-month loan deal and becomes Owen Coyle’s 12 summer signing following the addition of Nick Powell on a season-long loan from Manchester United earlier this evening.
Shotton said: “It’s been a whirlwind evening and we only found out really late about Wigan’s interest. I can’t wait to get going now and meet the players.”
