Antonio Conte has called on his men to start killing matches earlier, after the 3-2 win over Bristol Rovers.
Batshuayi and Moses got on the score sheet, with the Belgian picking up a brace. However, Bristol came close to equalizing with a Hartley goal in first half and a penalty in the second half.
And the former Italy boss wants his players to become more ruthless in their approach in order to prevent similarly nervy encounters in future.
“These games are very tough,” he told BBC Radio London Sport. “When you dominate the game, you must kill the game. In this case, we didn’t do this.
“It’s a pity because when you’re playing very well, creating a lot of chances to score, I don’t like to concede a soft goal from a free-kick and a penalty.
“We can improve this aspect, and stay concentrated until the end.
“We started [the second half] very well, created the situation to score another goal and then we conceded the penalty on a counter-attack. This created a bit of imbalance in the players.
“It’s important to understand that we must stay concentrated, always. And when you have the opportunity to kill the game, you must kill it, not keep it open.”
