Olympique Marseille president Pablo Longoria won't jump into a permanent deal for Manchester City fullback Issa Kabore.
On a season-long loan, Kabore's deal includes a permanent option for €20m.
The defender has also declared he wants to remain with OM long-term.
However, Le 10 Sport says Longoria wants Kabore to prove himself over the coming months before triggering the option.
So far, Kabore has impressed under OM coach Igor Tudor.
