Republic of Ireland midfielder Josh Cullen reserved plenty of praise for Dara Costelloe after the former Galway United forward's impressive debut for Burnley on the Championship's opening night.Cullen was making his first competitive appearance for the Clarets after following new manager Vincent Kompany from Belgian giants Anderlecht this summer and cemented a Man of the Match display as Burnley beat Huddersfield 1-0.But 19-year-old Limerick native Costelloe also caught the eye with an encouraging performance on the right wing as he made his first-team debut and maiden start for the club.Costelloe, who had made appearances for Galway in the First Division in 2018 and 2019, had previously featured for Burnley's Under-23s after signing two years ago.He had also been included on the first team's bench for the final seven games of last season as Burnley failed to avoid relegation from the Premier League."Special mention to Dara on his debut as well," Cullen told Burnley's official Twitter channel."I thought he was unbelievable for us and gave us great energy and quality, so we're obviously really pleased."#HUDBUR's man of the match on his 'brilliant' team-mates after our opening night victory
