Craig Dawson scored twice to help West Bromwich Albion to a 3-1 win over Arsenal at The Hawthorns, piling further pressure on Gunners boss Arsene Wenger.
The centre-back nodded home from a corner in either half, while Hal Robson-Kanu came off the bench to score the other just a minute after being brought off the bench.
Alexis Sanchez had levelled the game up for the visitors in the first half, but they were unable to leave the West Midlands with a positive result as they slipped to a fourth defeat in five league outings.

Tony Pulis "The most important thing is that we get that mentality into the players and into everyone around the football club that we want to get more points, that we want to push on. My aim is to get a team that can stay in the top 12 every year and get to cup finals. You've got to have that strong mentality and desire to do that."
Arsene Wenger: "Success, it's not down to me to judge that. Our job is to do as well as we can until the end of the season. We want to play in the Champions League next season. We have a tough job because we have six or seven teams fighting for the places. We are in the semi-finals of the FA Cup - we have an opportunity to [win] that as well."
