Real Betis - Valencia Football prediction

Lets go straight to my selected combination: 

Condition: 1-3 Goals. In my eyes both teams will score, no doubt Betis is in good form and rate them to find a net in front of home crowd. Additionally visitor knows that if you score at least one goal, than the task is half done before return leg, everything would be decided in own stadium within 3 weeks. In the dometic league, stats speak about goal as well, Valencia have seen more than 2.5 goals in 5 of their last 6 matches the same for Betis, in 5 of the last 7 matches. 

Condition: 2-5 Cards: Betis get averages 2,1818 cards per game, quite simple to say.  Mean while Valencia record 2,5. 

Condition: Corners: Betis averages 9,,74 corners per game (4,64 in favor and 5 against). Valencia, on the other hand, averages 8,73 (4,86 in favor and 3,86 against). 

We talk about semi-final Copa del Rey, like yesterday some fireworks, cards, goals and corners are on a card.
