It was confirmed on Monday that Pjanic would join Barca in a swap for Arthur Melo.
Paratic said, “Logically, the transfer market is part planning and part opportunity.
"In this particular deal, we had both elements. Pjanic is a very important player for us, so when the option emerged, we spoke to Miralem and he said he was happy here, so the only club he would've left us for was Barcelona.
“We found this player Arthur, who we had been tracking for a long time, and who is younger than Pjanic."
