So, after a tough battle at the London stadium on Thursday night, the Hammers pulled through to stay top of their group in the Europa League.
And it took a touch of brilliance from our two best performers of late, with James Ward-Prowse deftly lifting the ball into the box for Lucas Paqueta to slot home the winner.
It was a tricky encounter as Olympiacos were stubborn experienced European opponents who frustrated West ham at every possible opportunity.
But the worrying thing is that having gone ahead we lost momentun and but for the post, Olympiacos would have snatched a draw - possibly even deserved!
There's still plenty of football to be played in the Europa if the Hammers are to have European action after Christmas.
Back to the Premiership and frankly we are in miserable form after four successive defeats. The loss away to Brentford was especially disappointing as we did enough to win but managed to gift them all three points.
One cameo from that game has garnered much attention - with a 2-1 lead and seemingly coasting, we engineered a tap in for either Antonio or Benrahma at the back post. Bizarrely, the pair contrived to get into a tangle and put the ball wide.
And although our defensive leakiness is the most obvious problem right now, the form of Benrahma and Antonio is a close second in the concerning stakes. They both look devoid of confidence and really should be consigned to the bench today!
Forest are a difficult side with plenty of quality who will be salivating at the chance to have a crack at a befuddling West ham side. Quick on the break, Forest will punish any ponderous attacking that leaks turn over ball.
Up front, we lack shape and a clear plan. Mubama looks like a talent but he will continue to struggle with link up play unless he gets game time. Ings looks well off the pace and lost in Moyes' system. Antonio needs a goal badly - perhaps his old club are the side to do it against?
