Caliendo believes the firm stance to stick with Maicon will offer Inter plenty of collateral.
"Moratti refused a big offer from Real Madrid, and so I think this was Inter's best buy of the summer market," he told Inter TV.
"I don't think keeping Maicon was a surprise because the offer from Madrid was there and it was consistent, but Moratti had a fixed price on the player.
"It was a position which forced Madrid to withdraw. I would have done the same as Moratti."
