The free-scoring visitors looked home and dry as they moved into a 4-0 lead in the 74th minute at the Estadio Benito Villamarin, but 10 minutes later Betis had got it back to 4-3, only for Valencia to finally kill the game with two more goals at the death.
A bizarre game featured seven goals in under half-an-hour in the second half as Joel Campbell, Antonio Sanabria and Cristian Tello netted with smart finishes in a six-minute spell from the 79th minute to put Betis on the verge of a stunning comeback.
The visitors had looked set to win in far more routine circumstances when goals from Geoffrey Kondogbia and Goncalo Guedes put them two up at the break and, after Betis' Sergio Leon saw his penalty saved by the legs of Neto, Rodrigo and Santi Mina made it 4-0.
