Thomas Vermaelen believes the clinical edge Arsenal have discovered in their last two games can serve them well during the challenges ahead.

Arsenal have put five goals past West Ham and scored three at Brighton in the last week, without spurning too many other clear openings, and the captain knows that such a decisive edge can make all the difference in the Premier League.

He told the Official Matchday Programme: "We've been clinical in our last two games, converting chances into goals with efficiency.

"That's really important - the higher the level you play at, the fewer the chances you are likely to have in a game, so if you can get into the habit of taking them it's a big plus."

Doing so against Liverpool would help Arsenal towards a third consecutive victory, and Vermaelen says it is high time they embarked upon a prolonged run of winning form.

"It's important that we win and get on a bit of a run - our problem this season is that we haven't really put together a winning steak of more than three matches or so," he said. "We've played some very good games but have followed them with less impressive performances.

"What we need now is consistency - another win tonight would put us on the way to that and create some real momentum."
