'A grim, damaging afternoon': Lewis Cox on West Brom's poor Swansea defeat - WATCH
Lewis Cox gives his take on Albion's defeat, Steve Bruce's future and West Brom's current position.
Matthew Sorinola put the Swans ahead early on before Albion turned the game on its head.
Jake Livermore scored three minutes after the re-start and then Grady Diangana put them ahead 25 minutes from time.
But the Swans came back as substitute Oliver Ntcham levelled - before Albion were handed a golden chance to go back in front but Karlan Grant missed from the spot.
And then in the final minute of normal time Michael Obafemi came off the bench to sink the Baggies.
