Petr Cech has said that the next two weeks will determine the success of Chelsea's season.
The Czech keeper made a string of crucial saves during the Blues' dramatic Champions League victory over Napoli on Wednesday.
"In the next two weeks we have the chance to reach the FA Cup semi-finals, third place in the Premier League and take a big step in the Champions League quarter-finals," Cech said.
"One week ago, everything looked really bad for Chelsea but football is so crazy that it has all changed around.
"We won against Birmingham and Stoke and then came back from 3-1 down to beat Napoli and, suddenly, it all looks completely different for us."
Chelsea are currently fifth in the Premier League, four points off third-placed Tottenham Hotspur.
