WEST HAM UNITED manager, David Moyes, was left bemused and baffled after a controversial late equaliser from Callum Wilson denied his side all three points from an otherwise thrilling encounter on the south coast.
Long's flag had been raised nearly immediately as Nathan Ake's header went into the net via Wilson's head then shoulder.
Arnautovic took his tally to five goals in as many games with his late double, the first of which came after Asmir Begovic's slip when attempting a regulation clearance.
"But to overrule the linesman's decision, I couldn't believe". Offside. Which arguably you could say it is. When I saw the commotion I thought there was no way he would overturn it.
"The offside could be close, the linesman gives it as an offside goal but the worst thing is the Bournemouth player puts it in with the top of his arm so it should be ruled out for that".
"When the linesman's flag goes up you think "we've got out of jail there a bit", Moyes told reporters. "He said the assistant referee only put his flag up to draw attention to it, and I've never heard of that ever".
Goals from Dan Gosling and Nathan Ake had put Bournemouth ahead after James Collins had headed the visitors in front. We'd fought back although we weren't great throughout all of the game.
"I have no hesitation in playing any of them, so I don't think Jermain's injury forces my hand at all".
Even Bournemouth boss Eddie Howe admitted: 'It looks like we might have got away with one.
The 3-3 draw wasn't enough for Bournemouth to escape the relegation zone, though Howe was pleased that his side were able to refind their identity, as well as clinch a significant draw. "The games are coming thick and fast now and we need to go to Bournemouth and make sure we pick up some points".
