Gianfranco Zola has now joined the list of potential new Inter Coaches, as it's difficult to prise Andre Villas-Boas from Porto.
The club is scrambling to find a new tactician after Leonardo quit to become a director at Paris Saint-Germain.
Marco Branca flew out to Portugal last night for talks with Villas-Boas, who has a €15m get-out clause on his contract with Europa League winners Porto.
Not only is this difficult because of his commitment to Porto, but the 33-year-old also has offers from the likes of Chelsea.
Marcelo Bielsa turned down the job, while Sinisa Mihajlovic pledged his future to Fiorentina in a statement on the official club website on Friday evening.
There are numerous other alternatives, above all Delio Rossi and Gian Piero Gasperini, not to mention England manager Fabio Capello and ex-Turkey boss Guus Hiddink.
A new name mentioned on Sunday is former West Ham United manager Zola, who in Italy has only ever been assistant to Under-21 Coach Pierluigi Casiraghi.
