The midfielder believes his team cannot get carried away in the next match and reminded his team-mates of the recent draw against Belarus
The 1998 World Cup winners are currently at the summit of Group D, with 13 points from six matches, and could extend their lead if they win in Tirana.
Albania sit fifth in the group and though France are highly favoured, Diarra is taking nothing for granted.
"We will be facing danger if we approach the game the wrong way. We cannot underestimate this team, who have posted very good results in front of their own crowd," he said at a news conference.
"They also managed to beat Bosnia here, we have to be very alert and stay vigilant. We cannot make things easy for them."
France's last Euro 2012 qualifier ended in a 1-1 draw in Belarus and Diarra stated his side have taken a valuable lesson from that match.
"Against Belarus, we took 30 minutes to get into the match. That was fatal for us, even though we did not lose the game," the Marseille midfielder conceded.
"Now we know what to expect. Albania will not give us anything, it will be up to us to get a good result."
