The defeat, West Ham's first home reverse of the season, ended a five match league sequence of draws.
Had West Ham gained a point on Saturday, it would have been the first time West Ham drew six on the spin since...well, have a guess, and the answer is at the bottom of the page.
As for Rob, even with such a long and distinguished career as he has had, he has never been involved in such a defeat.
"I have never played in a game that went from 3-0 up to 4-3 defeat - and I don't want to play in any more either," he says.
"It is a long break now but that is life and you have got to get over these things - there is no point moping around.
"The result is over and we have just got to get on to the next game."
He insists a good run can get things back on track, and adds:
"The gap is closable, of course it is - all we need is a run of two or three wins.
"We know we are a good team but we have had some bad luck - as well as some bad play on Saturday - and we can bounce back."
Looking at Saturday more specifically, he adds:
"It started very, very well and unfortunately we let a silly goal in and did the same old thing, not controlling the game when we should have been.
"At 3-0 up you would expect West Ham to win the game, going on to get four or five - but unfortunately when they got that first goal the confidence seemed to go a little bit.
"Although they got a fantastic second the sending off certainly didn't help us.
"If you had a second look at it you would probably say Jermain didn't touch him but I think when someone is lunging in like that there is always a danger he is going to get red carded.
"If you catch him or not, if both feet leave the ground there is that risk; he made a meal of it - but unfortunately that is life.
"It was very difficult when they got it to 3-3 and they were putting pressure on us - we didn't want to let in the fourth goal but it happened.
"At 4-3 there was no coming back really; we were just trying to hoof the ball up to Brian Deane to get something - but it wasn't to be."
And the answer to the teaser about six draws on the trot in the league?
