Manchester United interim manager Ralf Rangnick says Jurgen Klopp and Pep Guardiola are the 'best coaches on the planet' ahead of this weekend's Manchester derby.
Liverpool and City are currently battling it out at the top of the Premier League table and the Reds will hope to close the gap on their rivals with a win over West Ham on Saturday.
The league title for the last four seasons has been won by either side, City have won three since the 2017/18 season, while Liverpool ended their 30-year wait for the prize in 2020.
