Best was sold to Blackburn in a £3million deal this week and feels he did not get a fair crack on Tyneside.
He said: “I loved my time at Newcastle but there was also a lot of disappointment there.
“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.”
