The 22-year-old shot stopper is likely to remain at Cork City for the remainder of the Irish league season if a deal does happen.
Harrington’s contract runs out at the end of the season, but Everton are keen to make a bid now to fend off interest from other English and Scottish clubs.

The keeper is keen to continue playing first-team football this season due to his international aspirations.
Harrington has been involved in the Republic of Ireland under-21 squad during their latest campaign.
Ireland face Israel next month in a two-legged play-off to quality for next summer’s European Championship.
Everton set to bid for Harrington
Harrington’s other motivation to stay at Cork City is their position in the league.
Cork are seven points clear at the top of Ireland’s second tier with six games to go, and securing promotion could mean the Irish could extend his loan further.
Described by his current manager as ‘very impressive’, Harrington could follow in the footsteps of one of Everton’s longest serving players by making the move to Merseyside.

Seamus Coleman was also signed directly from Irish football, and has since spent twelve seasons at Goodison Park.
Coleman is now club captain at Everton, and has proved that although it’s a big step up between Irish domestic football and England, it is possible to do.
Everton’s current number one Jordan Pickford was briefly linked with a move away from the club this summer.
England’s number one is at no risk of being dropped by Frank Lampard any time soon and looks set to stay at the club for another season.

However, the Toffees securing a promising young keeper could put pressure on Pickford in the future.
Signing Harrington isn’t the most important piece of business Everton need to do with the transfer deadline approaching.
Frank Lampard still wants another midfielder, but a deal for Harrington could be quite straightforward, and benefit the club massively in the future.
