Leganes goal was made possible because he got caught pushing way too high up, And they found acres of spaces where he was supposed to be present in the first place, Here is a quick quiz, Let's try and find semedo in this picture:

Nope, That's dembele near the referee, Semedo is actually out of the frame, In replay shots you can actually see him walking during their counter-attack, And getting exposed too high up on the pitch happens a lot with semedo, If anyone actually paid close attention to him since the start of the season, But due to his amazing pace, He many times can correct his mistake, But when fails to do that, This is exactly happens.
I really like semedo, He has great flair going forward, And great speed, But that isn't enough to make him an undisputed starter, And i don't blame valverde for opting to choose Roberto over him in some matches, While SR lacks that flair semedo has during attack transition, Roberto has much better decision making, When semedo improves that aspect of his game, He then would become our regular RB
