Sanchez put Arsenal ahead in the 34th minute at the Emirates when the ball bounced off Hull goalkeeper Eldin Jakupovic onto his wrist and into the net. Referee Mark Clattenburg allowed the goal to stand, but apologised to the Hull players after seeing replays of the incident during the half-time break.
When asked if the goal had been “fair,” Wenger said:
“Honestly I don’t know. I’m responsible for many things, but not for the refereeing decisions.
“So I feel sorry for Hull, but I feel that we had as well to cope recently with some decisions where you didn’t ask me this question. But I’m sorry, I want the right decision to be made.”
Wenger this week called Chelsea’s opening goal in the 3-1 win over the Gunners last weekend “absolutely scandalous” because of Marcos Alonso putting his elbow in Hector Bellerin’s face when winning an aerial duel against the Spanish right-back, who had to be substituted with a head injury.
Leroy Sane had also appeared to be offside when Manchester City took the lead in their 2-1 win in December.
“There are some other goals that we conceded, like at Man City, that nobody said that it was offside,” Wenger said.
The Arsenal boss also acknowledged that his team needed a break after last week’s two losses that left them 12 points behind leaders Chelsea.
“Of course. When you lose two games on the trot when you’re at Arsenal, you face a good storm, and there is only one answer, to win the next game, or you face even more,” Wenger said.
“I’m at Arsenal for 20 years, I know that, and when you look one day if I lost three Premier League games on the trot, you will be surprised.”
The second goal also came after a handball, as Sam Clucas stopped a header from Lucas Perez with his arm in injury time. Clucas was sent off and Sanchez doubled the lead from the penalty spot.
