I think the Champions League Final this time will be very fierce for El-Real, considering that Dortmund's defense is difficult to penetrate and has conceded fewer goals than Real Madrid, and it is very likely that there will be extra rounds, or even a penalty shootout to win.
Dortmund is facing an uphill battle against Real Madrid, considering Real Madrid really plays well and if so, Dortmund won't have much of a chance to lift the Trophy.
By scoring an early goal, Dortmund can put some pressure on Real Madrid and make a surprise result happen.
But we all know how difficult it will be for Dortmund to make Real concede an early goal.
