Manchester City boss Pep Guardiola says Chelsea counterpart Antonio Conte is one of the best coaches in the world ahead of the pair's meeting this Saturday.
The Blues have won their last seven Premier League games to hit the summit of the table and Guardiola hailed the Italian's impact at Stamford Bridge.
"Conte is one of the best coaches in the world right now," the City boss said. "I learned a lot from my time in Italy. They have no problem staying in the box for 89 minutes and using amazing counter-attacks.
"He made an exceptional job in Turin with Juventus and with the national team as well.
"You realise his strengths in his team. He has won seven in a row, and it shows how good Chelsea are doing.
"They were a contender to win the Premier League from the beginning, now maybe more than before. It's a good test for us."
