Arsenal boss Arsene Wenger says their upsurge in results has come from being tighter with their play.

Wenger believes a "less cavalier" approach has helped the Gunners take the maximum-points haul since losing at Tottenham on October 2.

"I would say we are a bit more controlled and less cavalier. We are less adventurous when the job is done, I must say," he said.

"You can feel that there is some reserve there if needed.

"In the second half against West Brom we just kept it serious without going overboard. Overall I would say it is a more mature attitude.

"We were more functional. We did the job properly, with quality and, I must say, with seriousness."
