Manager Mikel Arteta insisted Arsenal have taken the handbrake off after their 4-0 rout of West Brom. Alexandre Lacazette's second-half brace and fine strikes from Kieran Tierney and Bukayo Saka earned a dominant victory at the Hawthorns and the Gunners have now won three straight games in the Premier League for just the second time under Arteta. They rose to 11th, three points behind the top six, just weeks after their season threatened to collapse and Arteta was being questioned - but the boss can see progress. "This is as close as it gets to what we want," he said. "This is an Arsenal team with the idea I want. There were certain moments when we were very close to that. The players had the handbrake off and you can see they are free to play. "There were moments when we were really good, both defensively and offensively. "This is exactly what we want the players to do. The energy and the momentum is much more positive. "It is always tough to win away from home and we have done it in a really convincing way. It's three in a row and we had talked about the importance of this week." West Brom have now lost their last two home games 5-0 and 4-0 and have conceded 12 times in Sam Allardyce's three matches at the Hawthorns. They were outclassed again by the Gunners to leave them second from bottom, six points from safety, and Allardyce knows where they have to improve. "We have to battle on as a team, we can only do the things we need to do better than we're doing now. That is, first and foremost, to stop giving sloppy goals away. "We need to be more resilient in terms of our defending and, until we get clean sheets, we won't get enough points to move up the table because we haven't got any proven Premier League scorers in our squad."
