Victor Lindelof's agent says Barcelona tried to sign the defender from Manchester United after Matthijs de Ligt rejected them to join Juventus.
The Catalan side were one of the leading contenders to sign De Ligt from Ajax before he made a €75 million (£68m/$84m) move to Italy in July.
Barca were soon linked with Swedish centre-back Lindelof before the transfer window closed, but he ended up signing an extension earlier this month.
And the 25-year-old's representative, Hasan Cetinkaya, says Barca made several attempts to convince United to sell, but the club refused to let one of their top players leave.
"Lindelof was perhaps Man Utd's best player last season, and there was a lot of interest from clubs that are even better [than United] at the moment," he told Aftonbladet.
"When Matthijs de Ligt chose Juventus, Victor was pronounced Barcelona's first choice.
"His way of playing, his DNA, is very close to Barcelona's way of playing. He is one of the world's best centre-backs with the ball at his feet, and Barcelona wanted him. That's how it was. I can talk about that now.
"They contacted Ed Woodward on numerous occasions with concrete offers. I had a meeting with their transfer manager, Matt Judge, to try to make a transition. But they just said: 'There is no chance. Victor is one of our best players'.
"It ended up being a new agreement instead, even though Victor actually had three years left. Usually, they do not make extensions with players who have so long left on the contract, but when there was an interest at this level they had no other option."
Cetinkaya says Lindelof has come a long way since the day they met in a Lisbon restaurant while the Sweden international was still in the Benfica youth system.
"The day he signed the new contract was one of the finest moments I've had," he said. "I've been with him from the day he was an academy player in Benfica, and I met him and Maja (Nilsson, Lindelof's wife) at a very sunny little restaurant in Lisbon.
"Back then he was a kid with a little potty salary that he barely managed, and Maja was a girl who had left her job and all her childhood friends just because she believed in love. Two young people with big dreams, but with the same uncertainty.
"Victor wanted to become a world-class player, but worked with an agent who wanted to take him home to Allsvenskan. There was a clear agreement between Malmo and Benfica - only missing the player's signature - but then I came in after flying five hours from Istanbul and declared that he would ditch both the agreement and his agent.
"Within a few years, I guaranteed that he would play at world-class level - and everything has gone to plan. It is a completely indescribable journey. Now the future is secure for both him and his family. Now Ulrica Lindelof (player's mother) can sit back and see what she made possible when she fought with four children as a single mother."
