Should Alexis Sanchez's goal have been disallowed? Were Hull unlucky? And was Slaven Bilic right to feel aggrieved?
Dermot Gallagher joined us on Sky Sports Now on Monday morning to run through the big incidents from the weekend in the Premier League and abroad.
Read his expert assessment below...
Sanchez handball
INCIDENT: Arsenal take the lead through Alexis Sanchez, who handles the ball in as it ricochets off his arm from close range. Deliberate or unintentional?
DERMOT'S VERDICT: It's a moral dilemma when you think about it, because a handball has to be deliberate. Sanchez will say it is not, but it doesn't sit right with anybody that he scored with his hand.
The problem there is that it has happened so fast. Mark Clattenburg can't see it, the linesman from his angle thinks it has hit him on the chest.
The VAR (video assistant referee) will come, and the VAR will have looked at that and decided it was handball and it would have been cleared up. But with human error being what it is, he's got away with it.
Gibbs on Markovic
INCIDENT: Last-man Kieran Gibbs brings down Lazar Markovic as the Hull midfielder looks to take control of the ball and go through on goal. Gibbs is shown a yellow card by referee Mark Clattenburg.
DERMOT'S VERDICT: I think red. Because the law says the attacker must be in control of the ball or have the likelihood of being in control of the ball. All I can think is that Mark Clattenburg might think the ball is going away from Markovic.
Clucas handball
INCIDENT: Sam Clucas is penalised for a deliberate handball on the line, shown a red card, and Sanchez converts the penalty for 2-0.
DERMOT'S VERDICT: It is the right decision. It is handball, he's tried to stop it, he's put his hand out. Hull will look back and say 'there are two handballs and we've been penalised twice'.
Feghouli fouled?
INCIDENT: West Ham felt their midfielder Sofiane Feghouli was fouled by Chris Brunt in the build up to Nacer Chadli's opening goal at the London Stadium. Goal awarded.
DERMOT'S VERDICT: I looked at it over and over again, and the more you look at it the more you change your mind. The referee Michael Oliver was ideally placed. I just think it's one of those subjective decisions, some would say foul some would say not, so I'd stick with the referee.
Assistant sent off
INCIDENT: After Manuel Lanzini's goal was disallowed, Slaven Bilic's assistant Nikola Jurcevic is sent to the stands for protesting as Michail Antonio is flagged offside. Coming back from an offside position, Antonio moves towards the goalkeeper.
DERMOT'S VERDICT: It's definitely offside. If you look at this incident, the law says interfering with play or an opponent is offside, he actually impedes the goalkeeper so it's offside.
Bilic sent off
INCIDENT: Bilic himself was dispatched to the stand after West Brom's equaliser in the last minute. The Croatian threw a TV microphone to the floor, as Bilic felt that the Baggies took a throw-in from an incorrect position up the pitch in the build-up to the goal, and that the initial throw-in should have been awarded to the Hammers in the first place.
DERMOT'S VERDICT: The reaction is totally over the top. It's not acceptable from Bilic.
Ramirez's late tackle
INCIDENT: Boro midfielder Gaston Ramirez goes in late on Leighton Baines, stamping on his foot. Booking given only.
DERMOT'S VERDICT: I see this tackle and think, what's wrong? When you see the proper angle, it's a red card. A TV red card if you like.
Gabbiadini's handball
INCIDENT: David Moyes complained that Manolo Gabbiadini's opener for Southampton was a handball. The ball struck his arm, which was beside his torso, and went into the goal.
DERMOT'S VERDICT: No handball. It's struck him high on the body, but we have to sit down and say "this is this, this is acceptable, this is not acceptable."
INCIDENT: Against Sparta Rotterdam, Ajax's Joel Veltman points out to his opponent Ivan Calero that team-mate Bertrand Traore is injured on the ground, before running past the defender to cross. Nothing given.
DERMOT'S VERDICT: He will say it's ingenious, but it's certainly stretching sportsmanship to the limit.
