The Bosnian international was an emerging star at Lyon when the Gunners made their approach, a rather typical move from Arsene Wenger plucking top young talent from France.
The chance to go to Spurs came slightly later after Pjanic had joined Roma in Italy, with the London club looking for a replacement for Luka Modric following his 2012 exit to Real Madrid.
"There was the opportunity but at that moment I told them I was happy where I was and that's why we didn't sign the deal," Pjanic explained. "But I made my choice using my head and if I made that choice not to go to an English team it was for good reasons."
Having played Champions League football for Lyon, Pjanic flourished in Italy as he reached his mid twenties, finishing as Serie A's top assist provider in both 2014/15 and 2015/16. He also scored 10 Serie A goals in 2015/16 and earned a €32m move to Juventus that summer.
As the Champions League resumes this week for the start of Last 16 stage, the 27-year-old will face a Spurs team that he might have part of had things worked out differently.
