Los Che go into the game on the back of a stunning win against Atletico Madrid.
Baraja said, "It is a very important away game.
"It is an important test, so we have to face it with a great mentality and be competitive. I feel that Almería should have more points than they do at the moment. It will be very demanding in all facets. Away from home we have to continue with the performance we have shown at home.
"It is very important to start games well. Our mentality is to try to win. The most important thing is to once again have a clear identity, maintain continuity in the match and manage the different situations that may arise."
On their away form, he added: "In Seville we won by playing a complete game and in Vitoria the team fought until the end, but we got no reward for it. In Almería we want the team to show the same personality as we have at home."
