Real Sociedad - Rayo Vallecano

     They met in the La Liga at the start of this season here. Rayo Vallecano played on counters and created big scoring chances, making it 2-0 in the second half, only to concede a late goal to win 2-1 in the end. I am aware that Sociedad kept 5 clean sheets in a row at home, but Rayo is undefeated in 7 games in a row scoring in all those fixtures, 3 goals with Real Madrid at home for example, plus the 2-1 win from earlier this season here, and I back BTS once more between these two as Rayo kept just one clean sheet in those recent 7 games.
