Turnbull is looking forward to playing against the team he supported as a boy tonight.
The 25-year-old grew-up in Durham and was a huge Newcastle fan before turning professional with local rivals Middlesbrough.
"A lot of my family were supporters too and we had season tickets when we were younger so I'll be looking forward to the game," Turnbull said.
"Everyone likes to play against their boyhood team, so I'm looking forward to it.
"They seem to have done fine since they've been back up in the Premier League. I look for their results but my interest doesn't go much further than that anymore, and I'm sure they will have a good season.
"Everyone wants to play football and it's a good chance for me to play well.
"I'm not sure what the manager plans to do with the Carling Cup side. Last year Petr was rested but whether that continues I don't know, it is his decision and I'll go along with it, but from a personal point of view I'd obviously like to continue if we get through."
