Antonio Valncia is set to bring his ten-year spell at Old Trafford to an end this summer after United opted against handing him a new deal.
And Jamie Redknapp has advised Ole Gunnar Solskjaer to make Pal Pogba the new Manchester United captain.
David de Gea and Ander Herrera are two contenders to be named United’s next captain but Redknapp believes the armband should go to French World Cup winner Pogba.
"The most important bit of business Solskjaer can do this summer is to keep hold of Paul Pogba," Redknapp wrote in the Daily Mail.
"A couple of months ago, when Pogba was inspiring United’s astonishing revival under Solskjaer, the midfielder’s future did not seem in doubt. The return of Zinedine Zidane to Real Madrid has changed that. Pogba himself has said that he would be open to a move to the Bernabeu once his time in Manchester has ended.
"He may well feel that this summer is the right time to leave. Failure to qualify for the Champions League may not prevent United from attracting the best players but it could convince Pogba to go." Redknapp added: "Replacing a player who has contributed 11 goals and nine assists from midfield in the league this season is no mean feat.
"Personally, I hope he stays put. He is a player I have always loved to watch and the Premier League needs box office stars like Pogba. If United do keep him, they must make him feel a central part of the club’s future.
"I have argued before that they should make him captain and, with club captain Antonio Valencia set to leave, this is the perfect time to give Pogba the armband."
Manchester United remain fourth in the Premier League after Saturday’s victory over Watford.
