The Irish striker this week left the Magpies to join relegated Blackburn Rovers and although he mainly enjoyed his time with the Toon, he feels that manager Alan Pardew could have shown more faith in him last season.
"I loved my time at Newcastle but there was also a lot of disappointment there," he told The Sun.
"Last season I got a lot of assists alongside Demba Ba and got a few goals myself.
"No matter what you do, you still find yourself sitting on the bench.
"I love playing games and when you are sat on the bench it's not nice.
"I've never had a good run. Either injuries have hit, other strikers have come in or the boss hasn't given me a chance."
