Mourinho is known for his notoriously punishing training regimes, and has been ruthless with this Man United squad ahead of the 2016/17 season – a potent example being Mourinho’s decision to call a training session at 6am, right after his 25-man squad had flown back home from China.
Herrera posted a photo of himself and Juan Mata with the caption: “Let’s go for the second session of the day.”

Double training sessions are notoriously brutal, but they act as a cornerstone of Mourinho’s entire approach to football. The 53-year-old, wherever he goes, quickly forms a firm, dedicated and efficient unit of warriors with a seemingly unlimited oxygen supply.
Mourinho’s emphasis on moving quickly around the pitch as a fully formed, regimented side – one that can switch from sturdy defence to lethal attack in the blink of an eye – means that optimum fitness is necessary. Even more so, you could say, in the Premier League, a characteristically energy sapping environment. Mauricio Potchettino implemented double training sessions last year to great effect with Spurs last season, and is often done at various Championship clubs.
While double training sessions can lead to disenfranchisement in the squad and the danger of being overworked, reaching supreme levels of fitness – and sustaining it – is paramount for a side challenging for a title.
