Koeman was sacked as manager after Wednesday’s defeat at Rayo Vallecano left Barca well off the pace in LaLiga, with Laporta conceding he should have made the decision sooner.
Former midfielder Xavi, currently in charge of Qatari club Al Sadd, is the heavy favourite to be Koeman’s replacement and the pair have been talking.
Barcelona B boss Sergi Barjuan will take the team on an interim basis, starting against Alaves at the weekend.
“My opinion about Xavi as a manager is he is in a process learning, evolving, I have really good references from close people who know him better than me in that way,” he said at a press conference on Friday.
“I talked with him two months ago when we gave Ronald Koeman this confidence because I understand that we had to give him those months, the team needed some time to recover.
“I have a great relationship with Xavi, I have been speaking with him in the last month, I know his opinion about this squad, what he thinks has to happen. We talk as two friends and in this case my opinion is a really good one.
“I am talking to him because he loves football, he is a huge Barca fan, it is one of his goals in his life.
“If he is the one able to manage this squad, I have a great relationship with him and he is a possibility because we will see how everything will continue evolving.
“These are private conversations between friends and I cannot explain what we talked about.
“I already told you and I cannot explain anything about our options because it will not be professional and it will affect our plans. I am sorry, but I cannot tell you anything.
“I have always said one day he will be Barca’s head coach but I don’t know when. We have great references about Xavi at Al Sadd.
“All our reports about Xavi are positive. We can talk a lot about Xavi but I cannot give you more details. He is in all the papers, but we also have other options.”
Koeman got a vote of confidence several months ago, but Laporta accepts he should have been fired sooner in the season.
“Probably, yes,” he said. “Looking back it is easy to analyse, we felt Koeman deserved confidence to recover some injured players and it was a way to motivate the manager.
“I looked for some positives. Probably we had to make an earlier decision, I assume the responsibilities of this decision.
“The situation was not sustainable. We needed to act. We were not on course to achieve the objectives of the season, which is to win titles.”
Barjuan, who played 382 times for Barca in the 1990s and early 2000s, is happy to hold the fort.
“My objective is to win and have this team winning their games,” he said. “We are going to try and reverse the situation and I am going to try and add my grain of salt to change the dynamics of this team and the situation.
“If we see that things are going well then good, but if we need to take different decisions then we will do that.”
