Manchester City manager Pep Guardiola was full of praise for Tottenham Hotspur's head coach Mauricio Pochettino ahead of Sunday's game at White Hart Lane.
The Citizens are unbeaten in the English Premier League but face a tricky away game against second-placed Spurs.
The Spaniard admits it will not be an easy game as he urged his players to do their job in order to keep their place at the top of the table.
"I played against [Mauricio] Pochettino as a player and then as a coach," Guardiola told reporters.
"I think he's one of the best managers in the world - I enjoy watching Tottenham.
"He's doing an amazing job in London at Spurs. The way they play I like a lot - they're aggressive and have a lot of quality.
"The basis of the team is the national team with Alli, Walker, Kane - they have a lot of quality. Last season they were there until the last couple of games for the Championship.
"This year they're playing at a high level - they're in second position so it will be a tough game and I'm looking forward to going to White Hart Lane for the first time in my life. We will try and do our job."
