Inter Milan coach Jose Mourinho, whose side can win the title at home to Chievo on Sunday if results go their way, has sparked fresh controversy by joking that second-placed AS Roma will pay Siena to beat his team on next weekend's final day.
"If it's true that the president of Siena is happy to beat us and has promised the same prize to his players that he would have given them if they had stayed up, they'll have extra motivation," outspoken Mourinho told reporters.
"And who knows, Roma...might offer some extra money."
Inter playmaker Wesley Sneijder is a big doubt to face Chievo after injuring his thigh early in the 1-0 Italian Cup final win over Roma on Wednesday.
