The country's Under-21s exited the European Championships limply this summer but the Liverpool youngster, who skippered the Young Lions to victory at the Under-17s European Championships in 2010, feels that triumph can inspire his side to better.
"This squad have got a winning mentality. We have a core that have come up from winning the Under-17s tournament and others who did well for the Under-19s," Coady told reporters.

"You can either be here with the Under-20s or be on holiday somewhere and I'm sure all the lads with us would rather be here.
"I don't think you are going to improve unless you play in tournaments like this and test yourself against the best.
"During the Under-17s, we played against Spanish lads, like Gerard Deulofeu, who's at Barcelona, and a good striker called Paco. Paul Pogba is playing at this tournament for France and he's been playing for Juventus and has played in the Champions League.
"I like watching Spanish and Italian games and looking at how they play compared to us so I like to test myself against those types of players. You come away better at playing against different players and styles.
"I always believe you give your all for whoever you're playing for, whatever shirt you put on. You play for that team and you want to win for that team – whether I'm wearing a Liverpool shirt or an England shirt."
