Arsenal boss Arsene Wenger was happy with victory over Hull City.

But the win was filled controversy, from Alexis Sanchez's opener to a yellow card for Kieran Gibbs which could easily have been red after he fouled Lazar Markovic when the Hull winger appeared to be through on goal.

Wenger admitted his side rode their luck but said they needed the three points to regain their confidence ahead of their crunch Champions League tie at Bayern Munich next week.

Hull defender Andy Robertson told Sky Sports after the match that ref Mark Clatternburg had apologised to the Tigers at half-time for allowing Sanchez's opening goal to stand, but Wenger said he did not have a clear view of the incident.

"Honestly, I don't know," he said. "I am responsible for many things but not for the referee's decisions so I feel sorry for Hull but I feel that we had to cope recently with some decisions and you did not ask me these questions.

"So I am sorry. I want the right decisions to be made. There are some other goals like at Manchester City, that nobody said was offside.

"Of course (we rode our luck). When you lose two games on the trot at Arsenal you face a good storm. There is only one answer: to win the next game or you face even more. I'm at Arsenal for 20 years, I know that. When you will look one day if I lost three Premier League games on the trot, you will be surprised."
