Fifa agent Francois Gallardo has claimed that Pep Guardiola would have stayed at Barcelona, had the club sanctioned the sales of Cesc Fabregas, Gerard Pique, David Villa and Dani Alves.
The coach called time on his four-year spell in charge at Camp Nou in May, citing exhaustion and a need to recharge his batteries.
However, according to the representative, he could have remained in his post, but club president Sandro Rosell saw the quartet as untouchable.
"Guardiola announced his terms of renewal to Rosell. Among them was the sale of four players - Alves, Pique, Cesc and David Villa," Gallardo was quoted as saying by AS.
"Pep did not seem committed to Fabregas, Gerard and Dani, while the reasons for Villa leaving were sporting. He was especially disappointed in Cesc as a person, as he had refused to shake his hand when he signed.
"These players were regarded as untouchable, and the fans would not have accepted the sale."
Guardiola's successor, Tito Vilanova, has enjoyed an unbeaten league start with his side sat in first place, level on points with Atletico Madrid.
