Former Manchester United winger Bebe has not ruled out returning to Manchester United in the future.
The 25-year-old signed for United for a fee of £8m in 2010 but failed to live up to his price tag.
"I've never thought about [returning to Man United], but nothing is impossible," he told Portuguese newspaper Publico.
"If I score 10 goals in La Liga then for sure, I'll be able to sign for a big club. If I score 10 goals here at Rayo Vallecano I'm going to have many big teams chasing me again next year."
The Portuguese has scored one goal in six appearances for Rayo Vallecano this season.
