The Spanish giants and Celtic recently faced each other in the Champions League.
Luis Enrique’s side hammered the Scottish Premiership outfit 7-0 at Camp Nou in Group C back in September.
On Wednesday evening, Barcelona got the better of the Hoops 2-0 away from home at Celtic Park in Glasgow.
Barca president Bartomeu, who is 53 years of age, has outlined a similarity between the two clubs.
“The youth structure is so important to the identity of any club,” Bartomeu told The Glasgow Evening Times. “Almost 50% of our first-team players have come through our own club. They learn early how we play and they understand the culture of Barcelona and of the team.
“We can look abroad for other players to strengthen our team – but that is not my business. I leave that to the coaches.
“But when you have players who come through the club from a very young age they understand that it is an honour to play for the club – it is a privilege to wear our shirt. It is the same with Celtic.
“When you have that passion as a club then you have players who will give everything they have. That is what gives soul to the team. It is important to us, it is important to Celtic. It is why we have understood one another as clubs.”
Barcelona are one of the biggest clubs in the world and have some of the best footballers on the planet.
The Spanish giants have signed big-name players in recent years, such as Neymar and Luis Suarez, but they also have stars who have come through the academy, such as Andres Iniesta and Sergio Busquets.
Celtic are at the top of the Scottish Premiership table at the moment with 34 points from 12 matches.
Brendan Rodgers’s side will take on Aberdeen at Hampden Park in Glasgow in the final of the Scottish League Cup on Sunday afternoon.
