Real Madrid are very strong when they compete in the Champions League stage while Chelsea are currently having problems with their internal team, I think that it is very likely that Real Madrid can win here and advance to the next round.
Talking about the mentality of the Real Madrid team, there is no doubt because they are the team that has won the most Champions League titles of all time and of course against PSG is clear evidence that their mentality can beat PSG's star players.
Real Madrid have always been good at the champion league but with their present performance at the premiere league will real Madrid be able to beat Chelsea despite Chelsea's internal crisis, I don't think Chelsea will let that effect their championship performance?
The next round may be though for both clubs because of the other clubs like Manchester City or Liverpool who top the table in the just concluded premiere league round, let keep our fingers cross to see the outcome of top 5 clubs that will be playing in the championship this time.
