Claudio Ranieri has admitted that he should have done more to keep hold of Thiago Motta during his spell at Inter.
The Brazilian-born Italian international was sold to Paris Saint-Germain at the start of the year before Ranieri was sacked in March.
“My biggest error was agreeing to the departure of Thiago Motta,” the former Chelsea and Juventus boss told the Corriere dello Sport.
Ranieri replaced Gian Piero Gasperini last September – a Coach who has since admitted that he had issues with the club’s summer transfer policy.
Now Ranieri has also revealed that he had a difference of opinion with President Massimo Moratti about possible targets.
“Moratti told me on more than one occasion that he wanted to sign Carlos Tevez from Manchester City,” he added.
“If it was up to me, I would have tried to bring Mattia Destro back to the club instead.”
The latter, co-owned between Siena and Genoa, scored 12 goals for Serie A this term for the Tuscan minnows.
A summer move is expected with interest from Inter, Juventus and Roma.
