The Trinidad Express reports that Roberts has reached an agreement with the players to secure their services for Trinidad & Tobago (T&T), in contrast to previous seasons when they played for their respective IPL teams.
Pollard was part of the Mumbai Indians squad in 2011 when they won the IPL, Bravo plays for the Chennai Super Kings and Narine the Kolkata Knight Riders.
The report states that while an agreement had been reached between T&T and the three players in question, their respective IPL franchises are still expected to fight for their services.
Knight Riders team director, Joy Bhattacharjya, said on Twitter recently that the franchise's chief executive, Venky Mysore, had stated that Narine would play for his IPL franchise.
Roberts said that the details of the individual contracts had not yet been worked out, but that the players were close to signing a Memorandum of Understanding.
"All three players have said they want to play for Trinidad & Tobago. The government of Trinidad & Tobago have said they will match their fees, so that they will not lose anything," he said.
"We want the best team. Some of the Indian teams, the owners are obviously a bit upset because they would love to have Sunil Narine, Pollard and Bravo but I told them quite upfront that we are being professional, that we are not holding anything in secret. We are not going to wait until the last minute and then steal the players from under them."
Roberts also said he had spoken to the franchises: "I also explained to them, because some of them are quite upset ... I said, 'please for a moment, just picture Mahendra Singh Dhoni or Sachin Tendulkar or [Suresh] Raina deciding or contemplating to play for a club ahead of India. I don't think that would even be a choice. I don't think they would even be able to set foot in their land of their birth if ever they even consider disappointing their countrymen and their country by playing for club for money'.
"So while they may be upset, I tell them I am very sorry they are upset, but the [T&T] population wants our best players, the government wants our best players. The players want to play for Trinidad & Tobago and they will play for Trinidad & Tobago."
