Manchester United were 'blown away' by the 'immaculate' condition of Bruno Fernandes when he joined the club back in January.
The Old Trafford club's conditioning staff had drawn up a bespoke fitness programme so the Portuguese midfielder could hit the ground running in the Premier League after his £47million move from Sporting Lisbon.
But this plan was quickly ripped up during United's warm weather training camp in Marbella as it became immediately clear Fernandes had the necessary fitness levels to integrate with the squad.
Fernandes has made an excellent start to life at Old Trafford with his speed of thought in attacking areas giving United an extra gear in games.
And, according to the Metro, this is down in part to his high levels of fitness, with Fernandes ranking in the top three during physical tests in Marbella.
A source told the newspaper that Fernandes' team-mates have been 'blown away' by the abilities of the club's new signing.
He displays his qualities in warm-up drills, with United staff impressed with his sharp decision making and pass selection.
The 25-year-old also demonstrated the keen work ethic United wanted, putting in extra time on the training ground each day to practice free-kicks with fellow midfielder Fred.
He has already struck up a good understanding with striker Anthony Martial, leading the line for United in the injury absence of Marcus Rashford.
Fernandes has scored two penalties and contributed two assists in five appearances for United so far and will hope to increase those figures when they travel to Everton on Sunday afternoon.
He made his debut in the goalless draw with Wolves at the start of February, immediately showing his leadership skills by issuing orders to his new team-mates.
After the winter break in Spain, Fernandes delivered the corner from which Harry Maguire headed in United's second goal in their 2-0 win over Chelsea.
In last Sunday's 3-0 win over Watford, Fernandes converted a penalty kick and also created a goal for Mason Greenwood.
And his positive start to life at United continued in the midweek 5-0 Europa League win over Club Brugge as he slotted home another penalty.
