Ranieri had stated Inter could win the Scudetto this season, but concedes that's a dream too far now.
He said: "It's certainly not the luckiest campaign in Inter's history! We won't get sucked into self-pity, though. It could've been the turning point of our campaign to give us the confidence we needed, but instead we have to work even harder.
"Now we just have to keep quiet, work and let the other teams have their season while we have ours. If we drift away from the Scudetto race, then there are other very prestigious ones still up for grabs. I think positive."
