Carlos Beltran doesn't have to worry about pleasing anyone Friday night.

Returning to Citi Field for the first time since being traded by the Mets last July, the Cardinals outfielder said last night he is unsure how he will be received by Mets fans, but is ultimately unconcerned.

Beltran recognizes he was never embraced like teammates David Wright and Jose Reyes in his more than six seasons with the Mets and it was something he couldn't always understand while producing some of the best seasons in franchise history.

"There were times I felt like, 'What do I have to do in order to be one of their favorites?' " Beltran told The Post at a fundraiser he hosted for his Puerto Rico baseball academy. "Fans choose who they want to cheer for. I'm a quiet player. You're never going to see me out there showing a lot of emotion. I am who I am. When you try to be someone else then you're being fake to yourself, and I don't like to do that. I don't know how it's going to be [tonight]. They'll decide if they want to cheer or boo."
