Chelsea manager Thomas Tuchel says N'Golo Kante was key for their Champions League defeat of Atletico Madrid.

The Blues built on their 1-0 advantage from the first leg to run out 2-0 victors at Stamford Bridge and earn their place in the Champions League quarter-finals.

Hakim Ziyech opened the scoring in the first half and Emerson Palmieri came off the bench to score with his first touch in the closing stages.

But Kante stole the show in the centre of the park with his impeccable reading of the game and tireless work to win back possession.

"If you play with N'Golo you have half a man more because he has a volume that is simply outstanding," said Tuchel.

"It is a big gift for me, a guy so, so humble and a big helper on the pitch. Don't underestimate his quality."

Despite his side's comfortable victory over the Spanish club, Tuchel claimed Chelsea need to be more incisive when counter-attacking as they progress deeper into the Champions League.

He added: "We need to improve in counter attacks, the first contact after we win the ball when we implement more forward thinking to exploit space.

"We are a hard working team and a hard working team is the best team you can have as a coach.

"We want to be more clinical and with precise decision making with counter attacks. We are still lacking the last pass."
