Shane Duffy is adamant there is the qualities within the Republic of Ireland squad to improve their ailing fortunes.
The Boys in Green missed out on World Cup 2018 after a play-off defeat to Denmark but the FAI chose to stick with Martin O'Neill and give him the chance to regenerate an ageing group of players.
O'Neill has introduced a number of new faces to the party but they have struggled to gel, his side claiming just a single point from their three Nations League outings.

Monday sees them head to Aarhus to take on Denmark but first up there is Thursday's derby with Northern Ireland.
A victory would give the Republic a timely boost but Duffy is refusing to lose faith in the squad.
The 26-year-old is one of the few Premier League players at O'Neill's disposal and admits the country does lack quality in certain areas.
However, the defender feels the desire within the camp can more than make up for their shortcomings elsewhere.
"It's going to be tough, gelling and getting the right team again," Duffy told the Brighton Argus. "There are a lot of new players with not many caps. Two years down the line, when the Euros are here, they'll have played a lot more.
"We'll see, you've just got to be patient. It's hard because it's your country and it’s not nice, but we've still got a good squad with good players.
"If we get it together I think we've got a real threat. We've just got to back the manager, back the lads."
He added: "We might be short of a little bit of talent, but we've always got the heart and desire to go and try to win the game."
The Republic are 5/4 to win Thursday's friendly, with the draw 2/1 and NI 3/1.
