Nottingham Forest came out on top in a seven-goal thriller at the City Ground to climb out of the bottom three and leave Southampton on the brink of relegation.
Forest established a two-goal cushion on three occasions and each time, the visitors responded to pull themselves back into the contest. But Southampton could not manage an equaliser.
Now Southampton must win all three remaining games and hope either Forest do not pick up another point, or Everton fail to get more than one, otherwise they will be back in the Championship for the first time since 2012.
