Real Madrid this week appointed Zinedine Zidane as manager, after firing Rafa Benitez.
Zidane was not the club's first choice however, with Spanish football expert Graham Hunter making the stunning claim that they enquired after Pep Guardiola.
Guardiola is a former Barcelona player and manager, enjoying unprecedented success in leading them to two Champions League titles.
Hunter told BBC Radio 5 Live's Football Daily podcast on Monday that Real made the surprise enquiry, and were politely rebuffed, but that it never had a chance of being successful.
He said: "It's a fact six weeks ago they did approach him, and they did say, would you take over, and his camp... leaked out just to make it public deliberately that Pep gently said 'I would not go there, no thank you', but they did approach him.
"It tells you something about Real Madrid, that they could get it so vastly wrong, one of the anti-Madridstas since he was born, that they would approach him."
Guardiola moving to Real would have been an explosive appointment, and possibly generated as much outcry from Barcelona as when Luis Figo was a player.
He was Barcelona boss when relations between the two clubs were at their worst, with Jose Mourinho at Real.
The Spaniard is in his final season at Bayern Munich and is weighing up his next move.
