The 35-year-old, who spent a hugely successful loan spell at the Jakemans Community Stadium between February and April, has put pen-to-paper on an initial one-year deal to become a permanent addition to the United squad.

Grimes' 16 appearances in amber and black included eight wins, five clean sheets and one crucial goal at Forest Green Rovers.

His arrival bolsters a backline which has already welcomed George Ward, Lewis Shipley and Sai Sachdev this summer.

Fancy watching Grimes and his United team-mates in action during the months ahead? Season tickets remain on sale for the National League campaign – United's third season back in the National League.
