The 2017 champions have had six of their games postponed following their participation in the Caf interface-club competitions and Abubakar wants them to win against the Scientific Soccer Lads to serve as a big motivation for their Caf Confederation Cup Group A game against Raja Casablanca on May 16.
"We obviously need to win this game because it will serve as the right motivation ahead of the game against Raja Casablanca in the Caf Confederation Cup," Abubakar told Success FM.
"To play a high profile game on the back of a victory is the best of atmosphere one will relish to have so we have to use them as preparation. We need to improve game after game so that we can get to our destination this season.
"In Abidjan, we played very well especially in the second half but failed to utilise our chances. I want the players to put into practice all what we've learned in the last few days against Liberty, so that they can score as many chances as we'll get against Raja," he added.
Aduana sit 15th on the log with eight points while Liberty occupy 13th position with 12 points.
