Make your decision mate. Should they be underestimated or not?

Chelsea are really highly favoured for the trophy. There is nothing wrong with that considering the quality difference between 2 teams.
There is only one handicap for Chelsea here. They played a Champions League decider match in the Premier League 2 days ago. The fatigue will be their biggest enemy. If they deal with it well then I don't think there will be a surprising result.
It's obvious the difference in quality but we never know where the surprise will be, will Chelsea lose? That would be normal in my opinion.

The Premier league decider made Chelsea more determined to win and now they're doing that job again this final so I think Chelsea will win this one.
I wouldn't even be surprised if Chelsea lost dramatically.
