you are right Real Madrid will upset Chelsea. With Real Madrid's current form, it will be very difficult for Chelsea to stop them. Benzema in particular is in great form right now. Benzema has scored 6 goals in the last two matches. Benzema scored a hat-trick against Barcelona's strong defense. It will be challenging for Chelsea's defenders to contain Benzema alone. Also, young Vini is playing very well now. Chelsea's defense seems ineffective against Vini-Benzema and Modrich. At the Bernabeu we will only see the dominance of Madrid.
This match still has enough time for Chelsea to learn the strengths of Real Madrid. but true, on paper Madrid is superior to Chelsea, which is currently in a bad trend. however, that does not mean that Madrid will win the match later easily. at least, Fank Lampard is well aware of the strengths of Real Madrid's players. and, will not let them off the hook easily. the first task that Lampard has to do is, arrange for Chelsea players to play as a team. the rest, let luck decide.
On the other hand, we agree that the probability that Madrid has is very high to overthrow Chelsea, especially since the first leg will be played at the Santiago Bernabeu. I'm pretty sure Don Carlo will not squander this opportunity in the best way he can. because, it is not impossible that Chelsea can give a surprise. in football, anything can happen. So, let's wait and see what these two teams will do. in particular, Chelsea.
