The Marseille keeper has kept five cleans sheets in a row and credits his hard work in training with his good form between the sticksOlympique de Marseille goalkeeper Steve Mandanda says that sometimes he feels "unbeatable" after starring during his side's 0-0 draw with Lille.
The France international found his first-team place under threat earlier this season but says his hard work on the training ground is paying dividends.
"You have nights where you feel unbeatable," the 28-year-old shot-stopper told Canal +.
"I've been asked a lot recently. [Joey] Barton told me that it had been five matches since I conceded a goal.
"This season I've had a slightly more complicated period but now I feel good. The work in training has paid off. You must enjoy it but there are six games left to keep this concentration.
"Did I have any moments of doubt when I wasn't playing as well this season? No, because I've been here a while now and I know you can go out of form in a season. I did speak with the goalkeeping coach."
Marseille currently sit nine points off Ligue 1 leaders Paris Saint-Germain.
