Ajax goalkeeper Andre Onana is on former club Barcelona's radar.

Mundo Deportivo says Barca are exploring the prospect of bringing Onana back to the club this summer.

Onana is serving a 12 month doping suspension, which will run to December, though an appeal is scheduled to be heard in June.

Barca are watching developments closely, with director Ramon Planes and goalkeeper coach José Ramón de la Fuente in regular contact with Onana's minders.

A move for the Cameroon international would be made should Neto depart. Onana would arrive as cover for Marc-Andre ter Stegen.
