Nicklas Bendtner has revealed the lure of working again with Sunderland boss Steve Bruce was a major factor in his decision to join the club.
The striker, who played under Bruce at Birmingham during the 2006-07 season, is on a season-long loan from Arsenal.
"This has been a long time on the way," the 23-year-old told Sunderland's website. "Steve Bruce was the main reason behind me choosing to come here.
"This is a good opportunity. It's a chance to get my career back on track."
Bendtner moved back to Arsenal after helping Birmingham win promotion to the Premier League in 2006-07.
However, the Danish international, who scored both goals in his country's crucial 2-0 Euro 2012 qualifying victory over Norway on Tuesday, has slipped down the pecking order at Arsenal.
"I have not played consistently," said Bendtner.
"Being at Arsenal and sitting on the bench for a long time was not the ambition I had.
"Having played under Steve I know what he is all about.
"He plays an attacking style and likes to get the ball forward, which is something I value and is how I like to see the game played."
Bendtner could make his Sunderland debut in Saturday's home game against Chelsea.
