3 things we learned in the Premier League this weekend

With another round of Premier League action in the books, we take a look back at what happened in the English top flight over the weekend.

Bad vibrations under 'the Dildo brothers'

Does Slaven Bilic have a game plan at West Ham United? The Croatian's players have been restored to their factory settings, and that was evident when visitor Brighton & Hove Albion eased to a 3-0 win in Friday's match. It could've been more.

Bilic is out of his depth - he's much better suited to international management, where meetings are sporadic enough to leave his tactical flaws unexposed - but he's clearly working under co-owners with a bad track record in the transfer market and who constantly undermine him.

David Sullivan and David Gold - or, in a moniker coined by Sporting CP president Bruno de Carvalho, "the Dildo Brothers" - are the orchestrators of what looks like a possible relegation for the Hammers. The former is the most at fault, claiming Bilic refused to sign Renato Sanches and Grzegorz Krychowiak in the summer, and allowing his son to break club news via his Twitter account.

Vice-chairman Karren Brady is another guilty party, notably accusing West Ham of having "no culture" before moving to the oft-maligned London Stadium.

Right now, the West Ham boardroom is overseeing the excavation of a great club.

Koeman's on the brink

Maybe Ronald Koeman started to get the idea. Jonjoe Kenny was given the nod ahead of Cuco Martina, and Dominic Calvert-Lewin was again handed a starting berth. At long last, pace was being introduced, but greater aggression was the most evident change to Everton's play. It was eventually to the Toffees' detriment.

After Idrissa Gueye received his second yellow card on 68 minutes - the Senegalese midfielder or Ashley Williams receiving their marching orders seemed a certainty - a one-goal deficit had turned into a three-goal shortfall by the final whistle. But Arsenal was clearly the better side on Sunday and deserving of the win, with Calvert-Lewin's scraps when latching onto goalkeeper Jordan Pickford's clearances and Wayne Rooney's goal the only real positives for the home side.

The fact that Oumar Niasse - a player cruelly written off days into Koeman's tenure - could've scored the last Everton goal under the Dutchman was fitting. Koeman's player judgement has been found wanting numerous times over his Merseyside stint.

'If you have passion plus desire, you have no limits'

Huddersfield Town supporters provided a quote fit for motivational posters on Saturday: "It doesn't count how big you are or how experienced you are, if you have passion plus desire you have no limits."

Fans in the Cowshed, the nickname for the Leeds Road stand, helped inspire David Wagner's ranks to a 2-1 victory over Manchester United. The Terriers hunted in packs when United's defence had possession, but then dropped, narrowed their lines, and threw themselves in front of the ball when Jose Mourinho's lot advanced. It was valiant stuff from Huddersfield.

The Red Devils, who entered the tie unbeaten, were humbled in West Yorkshire, and they should be subject to an inquest in the coming days after their attitude was questioned by a weather-beaten Mourinho. For once, the Portuguese manager accepted a deserved defeat, and should take a valuable lesson from John Smith's Stadium.

Around the grounds

Liverpool's oft-mentioned impressive record against last season's big six has been quashed by this term's efforts. A 4-0 trouncing of Arsenal has been followed by sobering losses to Manchester City and, on Sunday, Tottenham Hotspur, registering a 9-1 aggregate defeat overall. If Reds fans want scant consolation, it's provided by Jurgen Klopp's substitution of Dejan Lovren after 31 minutes. Finally, the hapless defender's days in the starting XI may be numbered.

Life after Craig Shakespeare began with a 2-1 victory at Swansea City, with midfielder Vicente Iborra the pick of the bunch in a cohesive and positive display from Leicester City. Caretaker manager Michael Appleton is still an outside candidate for the full-time gig: his only successful stint on paper was in charge of Oxford United, but he inherited sinking ships at Portsmouth, Blackpool, and Blackburn Rovers.
