The Nerazzurri lost 1-0 to Olympique Marseille in the first leg of their Round of 16 encounter at the Stade Velodrome. Maicon went off at half-time and it's reported the Brazilian suffered a quite serious right knee injury.
"We knew they would get off to a very strong start, but we never gave in and created some chances that we failed to convert," Ranieri told Sky Sport Italia after the final whistle.
"This game is like a snapshot of our current moment, as when things go wrong then they really go wrong, but this tie does not end here. There are another 90 minutes to go and with a packed San Siro in the second leg anything is possible."
