The 46-year-old revealed that he is pleased with Les Gones' progress in their pre-season camp, regardless of the result against the Basque side
Les Gones took the lead in the second half through Mehdi Zeffane before new signing Aritz Aduriz scored twice late on for the Basque side.
However, the 46-year-old is remaining positive, insisting that his club are in good shape ahead of the new season.
"Players showed the state of mind that I was expecting. I saw some good things against a great team in Bilbao. The result is trivial," Garde told the club's official website.
"In central defence, I did not have much choice at this time. [Gueida] Fofana is not used to this position but has the ability to play there.
"Michel [Bastos] is the same on the left-hand side. It's very interesting but it may explain why we have not been able to hold the result late in the game."
