Former AFC Bournemouth player Shaun Cooper had a great season in the National League South last season, slotting into that well-drilled back four, just before Michael Walker sustained his cruciate knee ligament injury.
Cooper`s experience was vital in the Dolphins first season at Step 2.
He joined the club in 2016 from Sutton United, ensuring Tom Killick finally got a player he had been after for some time.
Cooper, who is best known by fans on the South Coast for his lengthy spell with the Cherries, can play at right-back, centre-back and central midfield.
