A victory against the already-relegated Tuscans will mathematically seal the title regardless of Roma's result at Chievo.
"We are not thinking about whether we could've done it already today, as we just need to focus on the face there is a genuine Final in Siena next Sunday," said the striker, who struck a wonder goal in yesterday's 4-3 win over Chievo.
"It's just a shame we lost our concentration in the second half, but we reacted and this is the important thing.
"Now we can rest for two days and we'll need to get ourselves at full fitness for the Final at Siena.
"Naturally I feel a little tired at the end of a long season, but that is normal at this stage and I'm fine."
