Mandanda wrongfooted: Valakari makes it 0-2 Finland
Finland scored twice in their visit to France, with the second coming through Onni Valalkari after a Mandanda mistake.
The French national team, with several replacements, took on Finland in a friendly before their Nations League games.
Forss opened the scoring in the 29th minute and, just two minutes later, it was Valakari who scored with a shot from the edge of the box.
The Finn profited from poor Mandanda goalkeeping, who was completely wrongfooted and left unable to do anything about the shot.
Didier Deschamps' side dominated possession, but it was Finland who scored twice in the first half take the lead.
