Manchester United chief executive David Gill has admitted he would not be surprised if Paul Scholes quit at the end of the season.
Scholes helped secure his 10th Premier League title on Saturday when he was introduced as a second-half substitute in United's 1-1 draw at Ewood Park.
Speaking to BBC Radio 5 Live's Sportsweek programme, Gill said: "It wouldn't surprise us if Paul Scholes retired. On the hand, we are enjoying the success we are having, so at the end of the season, he will have a conversation with Sir Alex about that."
Manager Sir Alex Ferguson is eager for Scholes to sign a one-year contract extension, like long-time team-mate Ryan Giggs.
However, the 36-year-old has his reservations after starting just 22 games in all competitions this term and has so far given no indication about his future plans.
United have no intention of rushing the midfielder into a decision and Gill, like his manager, would prefer Scholes to continue.
However, Gill has admitted Scholes could opt to follow fellow old-stager Gary Neville into retirement.
"I am sure he will let us know his decision and we will respect it," he added.
"He has been a brilliant player for many years. It is interesting that while Ryan got his 12th title on Saturday, that was Paul's 10th.
"It shows what he has achieved for us and what an absolutely fantastic player he has been."
