Jose Mourinho has hailed the "beautiful" performance of his players after they beat Sunderland 4-3 at the Stadium of Light.
Mourinho praised the attacking display from his side, but admitted that his players must tighten up defensively in future.
"We were really creative tonight and we played a beautiful game," Mourinho told BBC Sport.
"We were really creative and it was our best game of the season away from home. Eden Hazard was special tonight.
"However we conceded three from set pieces and we cannot concede like this in the future."
The win takes Chelsea to second in the Premier League.
