Pre-season training can be somewhat of a slog as players go through intense drills and routines in a bid to regain the sharpness lost over the off-season, while some also spend weeks away from their families on globe-trotting tours.
It is, however, not just the players who feel the effects of rigours of pre-season, with members of non-playing staff also becoming somewhat tuckered out by the preparations for the new campaign.
One person in particular who clearly suffers from the exertions of pre-season is Manchester United kitman Albert Morgan, who has managed the admirable feat of falling asleep on every coach journey of the club's tour of Australia and Asia so far.
Rio Ferdinand has been keeping supporters updated with Albert's sleeping patterns as part of #RiosTourDiary, having initially posted a picture on Monday of the man in question catching 40 winks.
Ferdinand has since caught 'Albie' quite literally napping once again - this time in Japan - with the much-loved backroom staff member in another deep slumber during a Manchester United coach trip.
This time, however, Albert woke up while Ferdinand was cheekily filming the Old Trafford veteran, who still appeared a tad too tired to respond properly to the questions of the Manchester United defender.
Rio Ferdinand will be providing more updates for #RiosTourDiary on his official Facebook page during pre-season. Like it here.
