For half a second the away end exploded as thousands of arms shot into the air and some of the West Ham players began to wheel away, but then everything stopped.
The assistant referee already had his flag raised.
Antonio had drifted beyond the last defender before the shot was struck and not by inches either.
The decision wasn't close, and the celebration died almost as quickly as it had begun.
"The flag's up," the commentator said.
"And West Ham won't get this one. Ward-Prowse nearly produces something special, but Antonio is clearly offside when the shot comes in."2
"No complaints with that decision," the co-commentator replied. "It's frustrating if you're a West Ham supporter, but he's well beyond the line.
This is one of the easiest decisions the match official has made all day."
On the touchline, David Moyes spread his arms briefly before letting them drop again.
He wanted to argue, but what was he even going to say?
