Chelsea boss Thomas Tuchel has insisted that there is "still room to improve" for the team despite their impressive performance in Sunday's 2-0 win over Arsenal.

Romelu Lukaku and Reece James scored the goals at the Emirates Stadium, as the Blues made it back-to-back wins at the start of the 2021-22 Premier League campaign.

Tuchel has praised his team's first-half performance but has said that the European Cup holders "could have played better" in the second 45 minutes of action.

"I was impressed with the result at half-time. We could have played better. We were not as sharp as we can be. We digest a long week as we gave them a big load with players coming in late," Tuchel told BBC Sport.

"From time to time there were heavy legs and sloppy in passing. But we overcame the difficult moments with quality and luck. We controlled the match in the second half. Still room to improve."

Chelsea, who also beat Villarreal in the UEFA Super Cup earlier this month, are next in league action away to Liverpool next weekend.
