Real Madrid will undoubtedly be favorites against Chelsea. Not only is Real Madrid in good form, but their squad is also very experienced. At the same time, coach Ancelotti is very experienced. Ancelotti knows very well how to perform in a competitive league like the Champions League. He can spot the opponent's weaknesses, and tailor his match strategy accordingly. Since Madrid's chances of winning the La Liga title are almost non-existent, their only target now should be the Champions League title.
Chelsea's performances have been erratic but this team is strong. And so Madrid must play carefully. Try to dominate from the beginning of the match. Chelsea's players will not get a chance to score in this match if Madrid starts to dominate. Even so, Chelsea's attacking performance is very poor.
Chelsea has a strong team with a clueless manager. They swapped one average coach for another. I have always been clamoring for Chelsea to sack Potter, when they finally did, they hired Lampard as an interim coach, who does that? Lampard was awful for Chelsea in his second season although he was better than Potter. With Lampard as Chelsea's coach, they will get ripped apart by Real Madrid. I'm not saying this because of how Chelsea is but also because of how much experience Ancelotti and Madrid have in this competition, especially at this stage. It will take a miracle for Chelsea to knock out Madrid.
You are correct. If Chelsea add a good coach to the team this time, hopefully the team will become even stronger. Currently, the team has some serious problems, which can be attributed to the weakness of the coach.
