"It's simple for me and the rest of the lads, we hope Ronnie stays," Ferdinand told The Daily Mirror.
"As well as being a United player, I'm a fan and my heart is with the club. So in that sense it's obvious what I'm going to say.
"We all want him to stay - players and fans alike.
"But it's up to Ronnie, the manager and the board. They decide what happens, we can't get involved."
