Pogba has been key to United's revival this season after delivering a string of impressive displays in the last month, which included scoring match-winning goals against Burney and Fulham.
Ferdinand, who was still at United when Pogba made his senior debut in 2012, feels the midfielder is now showing that he would want to leave a legacy at Old Trafford rather than leave.
"I don't know but whenever I've spoken to Paul Pogba, Paul Pogba is happiest when he's playing on a regular basis," the ex-United defender said on his YouTube channel FIVE.
"When he's playing consistently, when he's playing good football and when he's winning. He's a happy person.
"Manchester United right now must be a happy place for Paul Pogba to be. So, for him to go somewhere else, if they win the league I think it will be very difficult for him to walk out.
"I think a new contract will probably be on the table and for him to walk away from that, at the start of something he was very committed to when he walked through the door, he wanted to come here and win things and get Man Utd back on track to winning.
"I think he's the type of person who'd want to continue that and create a legacy at this football club. At this moment in time, if Pogba leaves at the end of this season – even if they win the league he hasn't created a legacy that he would've wanted to walking through that door."
