Lampard is managing Chelsea temporarily and there isn't any change in the team for now. They lost another game in the Premier League and the level of their morale must be quite down.
I don't see them being able to resist Real Madrid in their upcoming game. I think the same about the second leg as well by the way. Real Madrid can just beat them in both legs and send them home. Maybe Real Madrid aren't consistent in the La Liga but they are the opposite in the Champions League. They wouldn't miss the chance to eliminate this weak Chelsea here for sure.
The changing of the coach in this part of the season is hard and they have really slim chances to make it. Also from the other side Lampard is a Chelsea legend and if he can make it work and make a unity from the team maybe they can give Real run for their money.
With Chelsea's current condition, it is not an easy task for Lampard to fix what happened to Chelsea. The moral burden must be on his shoulders now, because Chelsea appointed him to take care of Chelsea temporarily. I'm not going to blame Lampard when they can't show any improvement. Indeed, now many hope that the miracle will come to Lampard to make Chelsea even better.
