Stepping out: Manchester City’s £51m striker Erling Haaland cut a casual figure in a Supreme T-shirt as he went for lunch in Marbella on Sunday with a female friend

Erling teamed his tee with a pair of pink cotton towelling shorts and white Nike sneakers.

He wore his blond locks out and over his shoulders and looked edgy with a pair of black sunglasses and a cap on.

His female pal kept things casual in a pale green skintight minidress which showed off her incredible figure.

Downtime: Erling looked relaxed as he stepped out, no doubt enjoying his time off. Erling has been given a fortnight’s break during the World Cup given Norway did not qualify

Erling looked relaxed as he stepped out, no doubt enjoying his time off.

He was recently dubbed the ‘best striker in the world’ by football manager Jürgen Klopp, 55.

It was reported last month that Erling’s obsession with sleep, diet and specialised training have been key to his success on the sports field. 

Erling is obsessed with proper sleep and how it improves performance, describing it as ‘perhaps the most important thing in life’. So he has worked at perfecting routines.

He wears orange-tinted, blue-light glasses in the hours before drifting off as they block out high energy emitted from natural light and digital screens.

Sleep is scheduled to start between 10pm and 10.30pm most nights, with electronic devices switched off way before then.

He is often not contactable, his phone on ‘do not disturb’ to avoid distractions.

His diet is balanced with carbohydrates — including his dad’s lasagne — and a love of fish.

‘Some players are scared of carbs after growing up in academies and needing to hit targets,’ one source said. ‘Let’s cut out rice, pasta… but that’s your fuel for running.’

He reportedly does extra training sessions to perfect his footballing technique and relies on meditation to help him focus.

He has played football all his life, being the son of professional footballer Alfie Haaland.
