Peterborough manager Darren Ferguson has completed the signing of former Swindon defender Claude Gnakpa on a one-year contract.
Gnakpa, 24, trained with Posh on their pre-season trip to Spain and played in Friday's friendly against Celtic.
Ferguson told his club's website: "Claude is a strong defender. He did well out in Marbella and we believe he will be an asset to our squad."
Gnapka has become Ferguson's final signing before the new season.
