Newcastle United winger Gabriel Obertan says the hunger to play first-team football was too great to remain a bit-part player at Manchester United.
The Frenchman, 22, scored once in 28 games in two years at Old Trafford prior to his move to St James' Park.
"I needed to play football, I do this job because I love football," Obertan told BBC Newcastle.
"Wearing a jersey because it's a big club is not worth it, I had to leave and Newcastle was the right choice."
Obertan added: "I have good memories [at Manchester United], we won the title last season, there was the Champions League final.
"But it was difficult playing with the reserves, trying to stay fit, and I didn't get enough games."
The former Bordeaux player joined Manchester United for an undisclosed fee in July 2009, having established himself in the French league with 'Les Girondins' and on loan at Lorient.
