Colchester have signed former Yeovil midfielder Joe Edwards, subject to paperwork.
Southampton have announced the signing of versatile defender Cuco Martina from FC Twente on a two-year-deal.
Valencia have confirmed the appointment of Ernesto Valverde as their new coach on a deal until the end of the season.
Valverde succeeds Mauricio Pellegrino, who was sacked just hours after the club's 5-2 defeat at home to Real Sociedad on Saturday.
Valverde, 48, has previously coached Athletic Bilbao, Espanyol and Villarreal in Spain as well as two spells with Greek club Olympiacos.
