"His behaviour and his state of mind are good," Blanc told a news conference ahead of Saturday's trip to Stade Reims, where Ligue 1 leaders PSG will look to extend their unbeaten run in all competitions to 34 games.
"I found him well, I talked to him yesterday. He told me they were up against a very good Portugal team. Of course there is disappointment," the 1998 World Cup winner added.
PSG, however, are the hot favourites to retain their Ligue 1 title as they lead second-placed Lille by four points after 13 games with third-placed Monaco five points off the pace.
They also look set to make it through the group phase of the Champions League and need only one point from their last two games to reach the last 16.
"We need to make sure we reach our club's objectives and he will be happy," said Blanc.
"It will soothe the disappointment of not going to Brazil. He is disappointed but he has a good state of mind and he will prove it on Saturday."
