Andrew Omobamidele, Alan Browne and Jason Knight come into the Ireland starting XI for tonight's UEFA Nations League encounter with Greece at the Aviva Stadium.Seamus Coleman was ruled out through injury, while Matt Doherty and Adam Idah have also been left out following the 2-0 defeat to England on Saturday.Nathan Collins has been handed the captain's armband in Coleman's absence, and the Brentford defender will marshal the three-man defence alongside Dara O'Shea and Omobamidele.It would appear that Chiedozie Ogbene has been asked to slot in at right wing-back, as he did on Saturday following a second-half reshuffle, while Robbie Brady retains his place on the left.Browne and Knight will come into the midfield alongside Jayson Molumby and Will Smallbone, who were left isolated in the defeat to England, yet it begs the question as to how Ireland will line up in midfield and attack.Sammie Szmodics looks set to lead the line, while perhaps Browne, Smallbone or Knight will be tasked with linking midfield and attack for the visit of the Greeks, who beat Ireland twice in the Euro 2024 qualifiers.Caoimhín Kelleher, as expected, will start the game in goal following an excellent outing on Saturday.Speaking before the game, the manager said that his selection offers the team flexibility, and he is hoping that his team enjoy more possession as they had in the England defeat.Republic of Ireland: Caoimhin Kelleher; Andrew Omobamidele, Dara O'Shea, Nathan Collins; Chiedozie Ogbene, Robbie Brady, Jayson Molumby, Alan Browne, Will Smallbone, Jason Knight; Sammie SzmodicsGreece: Odysseas Vlachodimos; Kostas Tsimikas, Lazaros Rota, Konstantinos Koulierakis, Ntinos Mavropanos; Andreas Bouchalakis, Manolis Siopis, Tasos Bakasetas
