'I preferred Mourinho to Guardiola'

Only eleven footballers have played for both managers, and one of them was 38-year-old Icelandic forward Eidur Gudjohnsen.

The legendary Iceland international enjoyed separate spells under the two coaches at Chelsea and Barcelona, and he looks fondly back at his time with Mourinho.

'I think Mourinho because my role under Mourinho was probably more important than under Guardiola', he answered when Soccer AM asked which of the two Manchester-based managers he preferred.

He played two seasons under Mourinho, while only spending one with Guardiola, which is why he had a better relationship with the current United boss: 'We had a stronger bond than with Guardiola', he said.
