Boss Mikel Arteta admits Arsenal have no room for error if they want to make a late Champions League charge.

Bukayo Saka’s first Premier League goal and Alexandre Lacazette’s late finish sealed a vital 2-0 victory at Wolves in the race for Europe.

The Gunners moved into seventh, three points behind Wolves, after a third straight top-flight win without conceding.

“We have to analyse, see the things we weren’t able to do and why that was. We were better in the second half so it’s a good starting point.

“It was not one of the best performances, the first half was no so good. Both teams were very balanced.

“The second half we started better with urgency and we had some chances but as the game goes by we knew they were dangerous on the counter attack.”
