Unai Emery has brought in some very strict nutritional measures for Arsenal squad

Football managers can occasionally be slightly petty

They, like people who aren't football managers, often like to have things their own way. They enjoy telling people something and they enjoy watching that person do exactly what they told them to do. As people, football managers sometimes go a little too far. We've all done it. We've all realised as children that we can convince certain friends or our younger siblings to do our bidding for us, so we do. We tell them that we desire a Freddo immediately, so they go to the shop for us. For managers, with multi-million pound footballers under their guidance and with jobs on the line, the stakes are a little higher, but they can still do as they wish. As such, it was a little shocking but not entirely unsurprising to hear that new Arsenal manager Unai Emery has brought in hilariously strict nutritional guidelines at the Emirates, which involves banning the drinking of fruit juice. Yes, fruit juice. Delicious fruit juice: the elixir of life. The drink you grab from the fridge, take a slurp out of, and suddenly you're ready for the day. Fruit juice (and particularly orange juice - not from concentrate) is one of the great juice joys in life. It can be as cold as icy water but as delicious as an orange, without the skin. Unfortunately, it is also quite high in sugar and it would seem that it is because of this that the Spanish coach has prohibited his players from ingesting it. The move resembles a similar one made by his predecessor Arsene Wenger, upon his arrival at the club in 1996. Wenger famously banned alcohol and junk food at the club, which at the time had what was reportedly a notorious drinking culture.
