Iceland legend Eidur Gudjohnsen has spoken of the differences between Manchester City boss Pep Guardiola and Manchester United's Jose Mourinho.
Gudjohnsen has played under both and in perfectly positioned to give an insight as to how they work behind the scenes.
He told The Sun: "Similarities are an eye for detail in the way that they work.
"In footballing terms, Jose is a little bit more defensive – not defensive-minded, but in the way that he analyses the opposition.
"Guardiola is more obsessed with the way that his team plays. And their personalities are completely different.
"Guardiola is more timid and doesn't like confrontation. Mourinho is more chest-out 'come and get it if you want'.
"Jose likes a bit of confrontation and a bit of discussion – and a heated discussion, at that.
"With respect, Guardiola would probably rather not have [that kind of conversation]."
