Thomas Tuchel’s decision to start a back-four against Brentford was a key reason behind Chelsea’s shock defeat at Stamford Bridge on Saturday, according to Paul Merson.
The former Arsenal star-turned-pundit was not impressed by the decision to shift from the Blues’ typical 3-4-2-1 shape to a 4-3-3, which left Thiago Silva and Antonio Rudiger exposed in the centre of the defence throughout the 4-1 defeat.
