Despite Vicente del Bosque's men stumbling to a draw against Finland, les Bleus' boss is well aware of the calibre of his opponents, adding they cannot afford to be apprehensive
A tame La Roja were held by Group I's bottom side in a toothless display on Thursday, but Deschamps has insisted his team need to be at the top of their game if they are to see off the world champions.
"Spain will force us to defend," the former Marseille trainer told L'Equipe.
"The best team in the world will be playing against us. Still, playing with just defence in mind will not be the solution. The game ahead will be complicated and difficult, but we cannot afford to be apprehensive.
"We will battle recognising the potential of this team."
Paris Saint-Germain midfielder Blaise Matuidi echoed his coach's comments, stating: "Deschamps reminds us not to get overly excited, but we showed that we were able to give them problems [during the 1-1 draw at Vicente Calderon in October 2012].
"We've already completed our first mission of enjoying playing together as a team."
Les Bleus currently boast a two-point advantage over their opponents in the qualifying standings, heading into the encounter at Stade de France.
