The La Liga champions dominated home side Malaga for the majority of the game, but only had Adriano's 25-yard strike to show for their efforts and came close to conceding an equalizer during the second half.
Without the services of star man Lionel Messi, Barcelona struggled to convert most of their chances and Martino admitted that his side needed to do a better job in grinding out results.
"We started off strong but our performance dropped as the game went on, we played a good first half in which we lacked effectiveness but we created a lot of chances," Martino pointed out to the club's official website.
"We controlled the game up until the 25th minute of the second half, but from that point on we lost possession. We have to learn how to close out games when we start to lose control."
Midfielder Cesc Fabregas believed the Catalan club's mid-week Super Cup clash with Atletico took its toll on the players, but he applauded them for coming away with three points.
"We had a good first half, but it’s true that in the second we lost a bit of intensity," Fabregas admitted.
"We’re still feeling the Super Cup match, and it was noticeable, but this was a very, very important victory."
The second leg of the Super Cup final tie between Atletico Madrid and Barcelona takes place on Wednesday.
