I think Chelsea are suffering from a culture shock in the first team. I mean we've been used to our experienced players (Lamps, Drogba, JT, Essien) coming up with outstanding performances in big matches for so many years...and then suddenly, this season, we have no leadership, no big game experience left on the pitch. Hazard and Oscar should become 2 awesome players in the next 3-5 years but at the moment, they are still learning the team's tactics and they are still getting used to each others style of play. You can't just let go of all your experienced players and suddenly expect the young players to step up in big matches. Look at Man United, Fergie still uses Giggs, Scholes in big games because he knows experienced players can keep coolheads in pressurised situations and thus, they can help the youngsters stay calm throughout the match.
