Striker Scott McDonald has insisted he did not fall out with Celtic boss Tony Mowbray to hasten his move to Middlesbrough.
Australia international McDonald, who this week joined the Teessiders in a deal understood to be worth around £3.2million, took the difficult decision to head south of the border in an effort to keep his World Cup dreams alive.
"I wasn't too happy with not playing as regularly as I would have liked," McDonald said.

"There was no fall out between me and the manager. They wanted me to stay at the football club but I felt I needed to get more game time.
"With the World Cup at stake at the end of the season, that was a massive factor also."
He added: "I had worked under [Gordon Strachan] beforehand and I believe I played my best football under him so it was another chance to team up with him and Garry Pendrey and try to progress even more as a player and keep getting better and better."
