Video: Master tactician Sam Allardyce shows how to get your message across
How to make a smooth change in formation
Correct us if we are wrong, but we think Sam Allardyce would like Blackburn to 4-4-2. Rather than get this message across as efficiently as possible, Big Sam decides to give his side their regular eyesight check-up.
The Rovers gaffer then realises that not only are his players struggling to see how many fingers he is holding up on the other side of the pitch, but also that he is lacking the third hand he needs to convey his message effectively.
He then opts for the hearing test for his players, which they also fail.
Brett Emerton wisely opts to utilise the more traditional method of one player coming to the touchline to receive the tactics and spreading the message to all of his team-mates.
