There were a combined 26 shots in that game with nine of them ending up on target. Under 2.5 goals was the recommended bet for that clash but a more open second leg looks the way to go for punters this time around.
Sociedad are 6/5 (2.20) to win the game in 90 minutes and Evens (2.0) to go through to the quarter finals of the competition. Another draw is 11/5 (3.20) with Betis priced at 47/20 (3.35) with 888Sport.
While they are outsiders to win the game in normal time, the potential for the tie to be decided on away goals means Thursday's visitors are favourites to qualify at 3/4 (1.75).
Those prices look tough to call with any certainty but what does look likely is plenty more goalmouth action between these well-matched Spanish sides.
Both teams to score has paid out in four of Betis' last five matches and at 10/11 (1.91) with 888Sport it looks the way to go here.
The only exception in that run was the first meeting between the sides but given the away goals quandary, both teams may be forced into being more aggressive this time around.
GoalAt Estadio Municipal de Anoeta, Sociedad have found the net in all but one of their five previous matches in all competitions.
Meanwhile, the only time Betis have failed to fire in their last five games on the road was a 0-0 draw in the Europa League when they were already leading their group.
That run has seen the visitors score nine times in all including a miraculous 4-3 win over Barcelona at the Camp Nou. They should be more than capable of finding the net in this game too with a place in the last eight of the competition on the line.
Despite the 0-0 draw last time out, both teams to score looks overpriced at 10/11 (1.91) with 888Sport given the longer-term trends involving these teams.
