Real Madrid can easily beat Chelsea in the Champions League.
This thing is becoming difficult to predict, It will not be as easy as expected now since Chelsea have sacked their coach and will get a replacement shortly. A new coach for Chelsea means their performance will not be easy to predict in the champions League and they can give Real Madrid a tough time as an improvement is expected. They lacked a good coach that fits the team, now they have the opportunity to get one. Also the game between Napoli and AC Milan than many also have easily selected Napoli as the winner may not go as expected too as in the Italian League where this two team have had a chance to play against each other first, AC Milan have dominated and winning in for Napoli by two goals even with the Napoli home advantage. The AC Milan coach can easily just replicate the tactics and strategy that he has used against Napoli in the Italian League in the Champions League and it may just work again. Things are generally unpredictable at this stage.
people might make Napoli the Favorite against milan, but the fact is that milan humiliated Napoli with 4 goals without reply in front of their supporters, this will be an important lesson for Napoli for their meeting against milan later in the UCL, while madrid and chelsea meet. I don't think anyone can predict that but people always underestimate Chelsea. even though if we see that they reached the UCL quarter-finals it was not something easy, they worked hard for it so against Madrid of course Chelsea had prepared for that.
