Dellaud has featured for Robbie Blake’s side in pre-season, starting Saturday’s 2-2 draw with Dorking Wanderers.
The promising full back played was dual registered with Moneyfields and near neighbours Chichester City last season after leaving Brighton & Hove Albion’s academy.
Dellaud’s first appearance as an ‘official’ Rock will come against one of his former sides when Miles Rutherford’s Chichester side visit Nyewood Lane on Saturday, fresh from a 9-3 victory over Brockenhurst at the weekend.
Welcome to Nyewood Lane, Eric-Georges!
