Tottenham defender Clement Lenglet feels they must improve when in possession.
The 27-year-old French centre-back has so far played seven games on-loan from Barcelona.
Tottenham are in third place in the Premier League but remain inconsistent.
Lenglet said, "Without the ball, we are the best team in the league. We run a lot, we are aggressive, we help our teammates. But we have to improve when we have the ball.
"It is important to say that we have made the best Premier League start in Tottenham's history. But we have dropped points against three big teams and we struggle against this type of team.
"That is the next step for us."
