Scholes has called it a day after making 676 appearances in a United shirt in whidh time he has helped win major trophies such as the Champions League and the Premier league no less than ten times.
Blackmore told Sky Sports News: "I was slightly surprised - he's a very quiet lad and he's gone out very quietly.
"We all knew Edwin (van der Sar) was going to finish, but I thought we might get another season out of Scholes. He played a big part this season in us winning the league and getting to the Champions League final."
Scholes was a key figure in the fabled 'Class of 92' which included David Beckham, Gary and Phil Neville and Nicky Butt.
Blackmore continued: "I played with him as a young lad and I thought he was the best of that bunch that came through - his awareness, his vision, he gets into the box and scores goals.
"You talk about Ryan Giggs, who's been fantastic at the club, and Scholes is in the same bracket - he's played nearly as many games and scored as many goals."
