Adam Lallana admits Liverpool must improve at defending set pieces if they are to challenge for silverware this season.
The Reds are third in the Premier League, level on 20 points with table-topping Manchester City, after beating West Brom 2-1 on Saturday.
But Liverpool endured a nervous last nine minutes after Jurgen Klopp's side conceded again from a set piece as Gareth McAuley smashed home from close range following a superb corner from Chris Brunt.
'It's a disappointment to concede from another set-piece,' Lallana told the club's official website.
