New Portsmouth signing Marcus Harness has confirmed his intentions to declare for the Republic of Ireland and is very much on Mick McCarthy's radar.

The pacey winger moved from Burton Albion to Pompey last week and with his club future secured, is now looking to the international game.

Ireland boss McCarthy revealed that moves are already underway to confirm Harness' eligibility for Ireland.

"Terry Connor and myself both saw Marcus play with Burton last season and we will have him watched again when the season kicks-off next weekend and see how he gets on," McCarthy told

"He has told us he wants to play for Ireland and we will follow through on that now and help him sort the paperwork from his side."

McCarthy is set to name his squad early next month for Ireland's crucial Euro 2020 qualifier against Switzerland and while the game may come too soon for Harness, the Irish boss has been keeping a close eye on Troy Parrott, who has impressed for Tottenham in pre-season.

Parrott started for Spurs against Juventus at the weekend and McCarthy believes that he's being prepared for a big season at the Tottenham Stadium.

"Troy got a start on Sunday against a top Italian side which was great for him. He is young and we have to remember that but this is good news for the player and for Ireland."

The Irish boss has also been keeping an eye on domestic matters and is following the European progress of Dundalk and Shamrock Rovers with great interest.

"I’m going to be in Dundalk that night as they continue to fly the flag in the Champions League," he revealed. "We will have someone at the Shamrock Rovers game against Apollon Limasol on Thursday night as well after their impressive win against Brann."
