Mauricio Pochettino admits Tottenham need to find more of a balance if they are to become genuine title contenders.
Three Spurs players have scored 10 or more goals in the Premier League this season for a tally of 55 but they have conceded 53 which Pochettino knows needs to improve.
"We are the only team with three players with more than 10 goals each - Harry Kane, Nacer Chadli and Christian Eriksen," he said.
"Not Chelsea, not Arsenal, not another team has three players.
"But we need to find a better balance between offensive and defensive and be more consistent. We need to improve a lot in our defensive situation."
Spurs currently sit sixth on the table, 10 points behind the top four, with two fixtures remaining.
