It's been a tough fall from grace for the 27-year-old, who was briefly Swansea' s record signing last year and their top scorer with 14 goals during an impressive debut Premier League season.
"I don't think I can keep him out of the team, he's done that well," Graham said. "Of course I've been frustrated, especially after last season.
"I thought I did well, we had a great season last season and this season started off quite well - I got a league goal (in Swansea's second game, against West Ham), a couple of Capital One Cup goals, then after the Reading game I found myself out of the team.
"It's frustrating, but that's part and parcel of football and it's about how you deal with it. I haven't been in to see the gaffer ranting and raving about why I'm not playing. I've got on with it, played Under 21 games to keep my fitness up and taken my chance like I did against Fulham."
