The Republic of Ireland international joined Blackburn Rovers earlier this week and revealed his frustration at not being given a fair crack of the whip at the Sports Direct Arena
Best penned a four-year deal with recently relegated Rovers on Monday after becoming frustrated with the lack of first team opportunites at the Sports Direct Arena, for which he blames Pardew.
The 25-year-old was a prominent figure alongside top scorer Demba Ba during the first half of the season but injury and the arrival of Papiss Cisse pushed him down the pecking order.
His last game for the club came in the 2-1 win over Aston Villa in February in which he was replaced by Cisse after limping off with a knee problem.
And despite enjoying his two-and-a-half year spell with Newcastle the Republic of Ireland international he feels Pardew treated him unfairly by consigning him to the substitutes bench when fit.
He told The Sun: "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."
Best struck 10 goals in 31 Premier League starts for the North East club after joining from Coventry in February 2010 and will now spearhead Blackburn's promotion push following his £3 million move to Ewood Park.
