Valence - Las Palmas Football prediction

Match back in this king's cup. In the first leg the two teams split on a parity score of 1-1. The return match takes place in Valencia. I see Valencia finish the job at home against the last team of Primera Divison. Las Palmas had a hard time out and even if it's a cup game, I do not see Las Palmas beat Valencia at home. The stats are in favor of Valencia at home and this is a qualifying for the next round !
