The Brazilian was linked with a move to Old Trafford but decided to join Barcelona.
Speaking to Four Two Two, he said: It almost happened with United. It was a matter of 48 hours, but Sandro Rosell had told me way before I got the offer: ‘If I become Barca president, will you come?’
“I said yes. It was only a matter of details with United when Rosell called to say he was going to win the elections there. And I had promised to him that I’d play for Barca… It was a quick negotiation.
“I told the English I had chosen Barca. It was the right choice. Brazilians have always loved Barca. We have a history there.
“Off the pitch it is like nowhere else in Europe, so we are always happy playing there.”
