Question: does away goal count in efl cup semi final

Answer: Yes, The League Cup is played as a knockout cup competition with each tie, except semi-finals, being played as a single match with the winner advancing to the next round. The semi-finals are played over two legs, with each club playing one leg at home, and the club that scores more goals on aggregate over the two legs advances to the finals. If the score is level after 90 minutes, or if the aggregate score is level for semi-finals, then thirty minutes of extra time is played, divided into two fifteen-minute halves. If the aggregate scores in semi-finals are still level at the end of extra time the tie shall be decided by goals scored away from home counting twice, according to the away goals rule. If the tie is not decided during extra time, it is decided by a penalty shoot-out.
