Grimsby have completed the signing of DR Congo international Jean-Paul Kamudimba Kalala on a free transfer. The 23-year-old former Nice midfielder has put pen to paper on a one-year contract with the Mariners having received international clearance.
Kalala made his debut for the League Two side in Friday's friendly against Rotherham United.
Manager Russell Slade told the club website: "I thought Jean-Paul did well, he will be very important for us."
