Antonio Conte is using video analysis to his advantage at Chelsea by having their training sessions recorded at their Cobham HQ.
Conte meticulously studies videos of matches and training, then uses the footage in team talks during the week and immediately before games to illustrate what he wants.
The 47-year-old used the same system at Juventus and with the Italian national team to great success.
Roman Abramovich has taken an interest, too, with the Chelsea owner having himself been shown the videos the players watch while visiting Cobham previously.
