Pep Guardiola has admitted he could clash with Arsenal boss Mikel Arteta - despite their close friendship.
Guardiola's Manchester City host Arteta's Arsenal in the FA Cup on Friday night, with both managers known for their animated and emotional conduct on the touchline.
Arteta, who was Guardiola's assistant at City for three-and-a-half years before taking over at Arsenal, has been criticised this season for his over-zealous behaviour towards officials. Guardiola, who can be equally passionate in the technical area, accepted the pair could have a bust-up because of their fierce desire to win.
