Barcelona played brilliantly, they defeated their opponent Dortmund by a huge margin of 4-0. In this match, Barcelona attacked so strongly that they scored four goals, their first match was a great win which ensured them to enter the semi-finals. However, Dortmund may not be able to win in the next match, Barcelona will attack even more strongly in the next match and enter the semi-finals, besides, Barcelona has the possibility of entering the final.
Not a proper topic to discuss CL, as that should be in UEFA Champions League 2024/25 Season, but let's put that aside. Barcelona made an unexpected result, that's because usually Borussia Dortmund can score at least 1 goal, if we refer to the last meeting of the two teams, even though they lost, Borussia Dortmund could still score 2 goals when facing Barcelona.
With those 4 goals, I think there's no more chance for Borussia Dortmund to advance to the next round, the next (second leg) is just a normal match that doesn't have high intensity.
Look at the odds for the 1X2 bet above, even at Borussia Dortmund's home ground, they're not the favorites. That's ironic for a big team like Borussia Dortmund.
