I still remember how Chelsea played against Newcastle United in the 29th Premier League match, 13 March to be exact. Newcastle were very focused on defending and Chelsea's players had almost no gaps to score, but K. Havertz arrived to score with a world-class finish in the 89th minute. Well, the 1st leg against Real Madrid, Chelsea will repeat that again. I'm pretty sure the game hasn't even started yet.
The Champions League has different pressures, equalising the EPL and UCL I don't think is appropriate. I know Tuchel is the defending champion but Anceloti he has more experience at UCL. The first leg may be chelsea will dominate with their trademark short uphill and possession. They certainly have a better mentality because they play at Stamford Bridge. But remember the second leg they will play at the Santiago Bernabeu. Of course a draw in the first leg and winning in the second leg is my prediction for Madrid.
