Graeme Souness and Micah Richards were mightily impressed by table-topping Chelsea and Thomas Tuchel as they overwhelmed Tottenham in an ultimately one-sided London derby.
After a first half which Nuno Espirito Santo's men shaded, Tuchel made the decision to take off an out-of-sorts Mason Mount and replace him with N'Golo Kante.
That switch, along with greater intensity for the visitors and a poor second-half showing from the Lilywhites, made the difference as Thiago Silva, Kante and Antonio Rudiger got on the scoresheet.
Speaking in the aftermath of the match which sent the Blues top, Sky Sports pundits Souness and Richards were quick to praise Tuchel's ruthless streak.
