Defensive decisions for Bilic
After a 4-1 thrashing, the first place to turn is always to the defence. Against Tottenham, West Ham saw disappointing displays from right back Carl Jenkinson and centre back James Tomkins, and manager Bilic should be considering changes for next weekend's game against West Brom. Whether it's Tomkins moving to right back and Angelo Ogbonna coming in to the centre of defence, or Ogbonna coming straight in for Tomkins, it was clear against Spurs that Bilic has decisions to make
Payet's absence worse than first feared?
When French playmaker Dimitri Payet suffered an ankle injury against Everton before the international break, Hammers fans knew that his three-month absence would be difficult. However, it became apparent at White Hart Lane that Bilic will miss Payet arguably even more than first feared. Manuel Lanzini slotted in to his central attacking midfield role and was as bright as ever, but West Ham certainly missed his creativity, with Bilic's men struggling to really create clear-cut chances without Payet's influence. This is something Bilic certainly needs to tackle if he is to keep West Ham around the top six.
Carroll should not be starting, especially away from home
It looked clear against Watford last month, but now there is no doubt - Andy Carroll shouldn't be starting for West Ham. The giant target man was virtually anonymous against Tottenham, and whilst he may point to a lack of service, he simply slows the play down too much, which is crippling for a counter-attacking team like West Ham. Carroll's best role may well be as an impact substitute, as he was against Chelsea - and his aerial presence in that situation helped West Ham win 2-1 having scored the winning goal; but for week in, week out football, Carroll shouldn't be relied upon by West Ham.
Diafra Sakho isn't a winger
Payet's absence meant that Lanzini moved in from the right to the centre, and Bilic made the strange decision to play striker Diafra Sakho out wide on the right. Unsurprisingly, it didn't work. Sakho struggled to have an impact going forward, and he offered Carl Jenkinson very little defensive protection. It's a tactical experiment that Bilic cannot afford to repeat, with summer signing Michail Antonio a much better option to be playing out wide than Sakho.
No need to panic
Some West Ham fans were clearly distraught after the game, and whilst it was a hugely disappointing result to lose to such a fierce rival, the Hammers can bounce back from this. Bilic has led the club to some huge results already this season, having beaten the likes of Arsenal, Chelsea, Liverpool and Manchester City. This defeat certainly hurts more than others considering that it was against Spurs, but supporters should maintain their belief in Bilic after a promising start to the campaign.
