Capello’s contract with England is set to expire after Euro 2012, but reports in recent days claim he could leave after the World Cup this summer.
Trapattoni told Italian TV station RAI’s ‘GR Parlamento’ show: “Even before Mourinho left, I imagined the name of his possible replacement.
“Inter’s next coach? At this time, Capello is the No.1 candidate.
“There’s no doubt about his wish but it depends on his contract.”
He added: “I think it will depend on his contract but Moratti even in the past had the possibility to sign him.
“Knowing Fabio, he is very focused but his situation is very difficult and he is followed by everyone.
“Ahead of a World Cup, a false step could create problems for him.”
