Rakitic's arrival at the Nou Camp follows the sale of Cesc Fabregas to Chelsea, while 34-year-old Xavi is also set to depart Barcelona this summer, even though his expected move to Qatari club Al Arabi has reportedly broke down.
In a farewell press conference at Sevilla's Ramon Sanchez Pizjuan stadium on Monday, Rakitic eschewed any comparisons with either of his fellow midfielders.
Rakitic was previously criticised by Sevilla's president Jose Castro for his conduct in the transfer, turning down an offer to renew his contract with the Europa League winners earlier in the season.
However, the midfielder insisted he had acted appropriately.
"I don't regret anything I was always open and correct, that's why I say that the people that have been most important to me recently have been the president and [sporting director] Monchi, I never tried to force an exit and they know that," he said.
"I'm very proud that the president didn't want me to leave, that's positive. But an offer arrived that appealed to me and the club.
"Sevilla was always my first option. I asked for time to evaluate certain things and I've decided to take a step forward in my career and try and fight for more trophies. Last year my team-mates left but I stayed because I wanted to achieve big things. Now the time has come but I was only thinking about football."
