The Blues' season was dealt a further blow on Saturday as they crashed out of the FA Cup following a penalty shoot-out defeat to Everton at Stamford Bridge.
They take on FC Copenhagen in the UEFA Champions League this week as they look to salvage their campaign - with the Premier League title race slipping out of their hands as they trail Manchester United by 12 points.The Italian believes only Petr Cech, John Terry and Branislav Ivanovic are playing anyway near their best and admits that confidence is low following the Toffees defeat.
He said: "How many players are playing near the top of their level at this moment besides Cech? Ivanovic, who is playing consistently. Terry.
"A couple are not at 100 per cent fitness. Frank Lampard played well against Everton.
"We have lost confidence in our play, we have no continuity. That is the reason for these results.
"Saturday was not good, we are disappointed. But the performance was good, we worked hard for 90 minutes. We created 10 chances.
"We have to stay together, work hard."
Chelsea travel to Denmark for their last 16 clash with Copenhagen on Tuesday night, hoping for a positive result to leave them with something still to play for this term.
