Here's the BBC sport of the goal...
"GOAL - West Ham 1-1 Southampton
Michael Obafemi
As a say that, Southampton equalise.
This has come from literally nowhere.
James Ward-Prowse, who has been in the thick of the action so far, is released down the right-hand side of the area. His cutback finds Michael Obafemi, he doesn't connect cleanly but his effort loops in the right-hand corner to pull the Saints level.
Big goal at the bottom of the Premier League."
