'Jeff Hendrick set the bar too high at Euro 2016' - O'Neill

Hendrick, along with Robbie Brady, starred for the Republic of Ireland in France as they made it to the last 16, where they gave the hosts an almighty scare before bowing out with their heads held high.

Prior to Saturday night's Nations League game with Denmark at the Aviva Stadium, the Ireland boss told the 'Daily Mail': "He was part of a side that actually did go 11 games with one defeat, and we never lost in a game away from home.

"We went to some difficult places - Serbia, in fact he scored a goal out in Serbia - so he had reached a very high performance level in the Euros, and so the expectation on himself and Robbie Brady and the likes of Seamus Coleman did become very high.

"It became high with all of us and I think it became high with himself as well. Sometimes whatever you do, maybe you don't reach that sort of level, but that was very high.

"I just think you have to give him a little bit of slack here. He's done exceptionally well. There are some games where he didn't do so well, but the very fact is that we're judging him now on the performances that he made out in France", O'Neill added.
