The Irishman has seen his appearances limited this season due to a lack of fitness following two serious knee injuries, restricting him to just one start. O'Neill praised the 22-year-old's attitude, but admitted that a lack of playing time and forthcoming opportunities was an issue that would have to be assessed.
"It's been really tough for him. He's been involved in the squad but he hasn't started and of course it's frustrating,'' O'Neill told the Sunderland Echo.
"It's something we would look at in the summertime. He's a genuinely good lad. He hasn't moaned about it to me, but he did say he would like to play.
"His first choice would be playing for Sunderland, but at some stage or another he has to play."

With O'Neill drawing up transfer plans in a bid to put his own stamp on the team, the midfield seems to be an area with depth. The likes of captain Lee Cattermole, Jack Colback, Sebastian Larsson, James McClean, David Vaughan, Craig Gardner are all battling it out for places.
While Meyler may currently be behind in the pecking order, he is determined to recapture the form which saw him earn a squad call up for the Republic of Ireland two years ago.
"Obviously, I haven't played as much as I would have wanted to, but I have never even considered leaving or going out on loan'," Meyler stated.
"I haven't gone knocking on the manager's door or anything. I just want to do my talking on the pitch. I want to play for Sunderland and I want to play for the manager.
"I will do some work over the summer and aim to come back for pre-season fitter than ever. I'm just looking forward to a full pre-season, because it is very hard to catch up if you miss out on that."
