Despite a difficult start to the season in LaLiga Santander, Laporta was keen to express his support for the current boss.
"He's a Barcelona great and he deserves a degree of confidence," Laporta said of Koeman.
"This degree will be determined by results and performances, which is the law of football.
"I encourage him to pick up the baton and guide the players because anything can happen in football.
"Each person has their own way of expressing what they feel and each person has their own way of motivating people.
"I saw that in the first campaign we had with [Frank] Rijkaard. The first half of the season was disastrous and then we missed out on the league by a very small margin. We had a historical comeback.
"I'd tell [the current players] not to let their guard down and go for every [competition]. This can be difficult but, in football, experience tells me that lots of things can happen. We have players to turn the situation around and bring back the joy and winning mentality."
