Adam Webster replaced the Irishman in the back three that faced Manchester City at the Etihad before the international break, and Duffy recognised that the competition for places in defence is as strong as it’s ever been.
He said, “I probably deserved to be left out because I hadn’t played that well and I’m still adapting to a new position.
“I’ve got to keep working hard to stay in the team and that competition will only push me to improve. You shouldn’t think that you’re going to play in the team every week and I understood the manager’s decision, because this club is more important than me.
“I knew I was good enough to get back in the team, so I kept pushing and the manager has been fair with me.”
The Irishman spoke about adjusting to playing in a back three under Graham Potter, and praised Webster and Dan Burn for the quality they have shown this season.
“It’s a different position for me playing out on the right of a three and it means I am coming into midfield a lot more.
“I’m still adapting to the position as I’ve only played three games there. Webby is a good player and Dan has been brilliant all season, so I understood the decision when I was left out. It gave me a kick up the backside!”
The defender also spoke about the progress of compatriot Aaron Connolly and believes the forward needs to stay grounded in order to establish himself in Potter’s plans.
“We all know he’s got a bright future, and he’s just got to keep working hard to battle for his place. He knows there are only two other strikers at the club and he’s the third one, so he’s going to get chances.
“He’s someone with a big future, and it’s important he doesn’t change his mentality so that he continues to push for a place in the team.
“I try to keep him level-headed because he attracts a lot of attention and he’s only young. I’ve got a lot of games under my belt and it’s about trying to look after him.”
