Madrid is indeed difficult to predict against a great club and has beaten it like Barcelona, but I think against Chelsea later it will not be difficult for Madrid to get rid of him because Chelsea's performance has been very bad since Potter left who was also replaced temporarily by Lampard did not make the slightest change even because yesterday they lost against Newcastle, so since seeing the way they played yesterday it was really not convincing to qualify for the UCL to the next round.
Basically I agree that Chelsea really needs a competent manager to make the team better. Lampard is manager whose experience has not proven to be good, has not been able to prove many things and that makes him have to learn a lot about coaching. Maybe there will be a time when Lampard is as successful as a coach as Arteta was at Arsenal, but I don't think that will be the case for him this season.
Real Madrid excel in many ways, apart from competitive experience, they excel in terms of the quality of the players and the experience of the coach. Lampard vs Ancelotti, it's not comparable but it's always possible to win a game because it all depends on the chances on the pitch. The Champions League is unpredictable, but Real Madrid is a team that is generally more stable compare Chelsea.
