Chelsea manager, Xabi Alonso, has explained why they suffered a 2-0 defeat at the hands of Tottenham on Saturday.
It is the Blues' first home defeat in the Premier League this season.
Mike Penders' own goal gave Spurs the lead before Cole Palmer was sent off after two yellow cards.
Mathys Tel then produced a moment of individual brilliance to seal a rare victory.
"We are all disappointed with the result; with the performance collectively and individually, we were not at our best level," Alonso told reporters.
"It was about the first goal and it went their way and with 10 men it was difficult, but we can do better.
"Chances were the main thing; they had few and we had few. We spoke at half time we had to be patient and be mature.
"We can do better.
"We wanted to have this fluidity in the middle. We wanted pockets filled with Cole Palmer and Morgan Rogers. There were situations, but overall we have to do better."
