However, despite the Spanish giants making three bids, the Reds held firm and kept the Brazil global.
The Catalan giants are expected to again try and sign the creative midfielder in the January window after their failed mission last summer and Iniesta admits that the Brazilian is the kind of player who would perfectly fit in at the club.
Now midfielder Paulinho has waded in on the potential transfer, despite Barca finding themselves in hot water this week for allegedly tapping up Antoine Griezmann without Atletico Madrid's permission.
The 33-year old joined the club from Liverpool in 2010 and has thrived as a centre-back in the past seven years.
Rakitic feels he still has plenty of years left in his legs and doesn't want to spend them as a bit-part player - even with the prospect of more title glory at Barca. "Everyone expects the great players to come to Barcelona, we have a very strong group of great players, without Coutinho people are doing a great job".More news: Pentagon confirmed existence of UFO program, incident videos released

And Paulinho, in an interview with Deportivo Mundo, has said the transfer would "bring him a lot of happiness" and said Coutinho would make a difference to Barcelona.
"I want him to come, I think it would be a great signing for Barça".
"He is player with a profile that suits us and would be a great signing if he finally arrives".
The same report states that the agent put an agreement on the table from the Liverpool owners, stating that the Reds are willing to sell Coutinho for £133million.
However, Klopp has stressed that both players will be fully focused on Liverpool's busy schedule over the festive period.
