The Sunderland centre-back praised the 24-year-old, insisting that his decision to foul the Atletico Madrid attacker kept the Boys in Green in the game
John O'Shea is adamant that Shane Duffy had to foul Antoine Griezmann and take a red card in the Republic of Ireland's Euro 2016 last-16 encounter with France.
The Boys in Green succumbed to a 2-1 defeat at Parc Olympique Lyonnais on Sunday, with Griezmann striking twice in quick succession after the re-start to cancel out Robbie Brady's opener.
Their task was made considerably more difficult when Duffy was dismissed for a foul on Griezmann that denied the Atletico Madrid forward a goal-scoring opportunity on the 66th minute.
