Pep Guardiola expects Manchester United to provide Manchester City with a quality test in Sunday's derby, as he comes up against Erik ten Hag for the first time.
Guardiola and Ten Hag were both at Bayern Munich when the former was manager, and they have been full of praise for each other previously. Now, ahead of Sunday's first derby of the season, Guardiola said he has been impressed by United's progress in a short time under Ten Hag, warning his City players to be ready for a tough game.
United have overhauled their squad this summer, with a number of new signings set to feature at the Etihad - including Argentine defender Lisandro Martinez, who Guardiola said will be dangerous if City underestimate him purely because of his height.
