Both men were joint-winners of the overall title last year
Martin O'Neill and Michael O'Neill have been named as joint-winners of the Philips Manager of the Month award for June.
The two men led the Republic of Ireland and Northern Ireland respectively to the Second Round of Euro 2016. It is the first time both teams have played in the finals of the same international tournament.
Martin O'Neill led the Republic to the European Championships at the first time of asking. His side beat Italy and drew with Sweden, before being eliminated by hosts France in the last-16.
Michael O'Neill's team played in the European Championships for the first time ever. A 2-0 win over Ukraine was undoubtedly the highlight of the tournament, before they were eliminated by Wales.
Both men were last year named as the joint winners of the Manager of the Year award for guiding the two countries to Euro 2016. After their respective performances in France, they may be repeat winners.
