Piiroja: Estonia can still qualify
Estonia head to the Faroe Islands to take on the group's bottom-side tomorrow, and victory there would leave Piiroja's side one point below second-placed Slovenia.
Piiroja said the players had already shaken off their disappointment at losing 3-0 to the Italians and were feeling confident.
"There is a fun atmosphere in the squad, and although it's only a couple of days since the Italy game, the team's spirit has not been affected," he told Eesti Paevaleht.
"The new game is already in sight and nobody is crying over Italy. In Italy we did not necessarily expect to win, but against the Faroe Islands we can get three points to bring us back into it."
While Italy look like running away with the group, Estonia remain in a tight battle not only with Slovenia but also Serbia and Northern Ireland.
Estonia begin the match one point behind Serbia having played the same number of games, while Northern Ireland are one point behind with a game in hand.
