4. Mourinho gives it a real rattle in the second half, but Son sees red
When Mourinho ran down the tunnel on the cusp of halftime, the frame around the Tottenham Hotspur stadium knew their players would pay witness to the other side of the Portuguese mastermind, far from what he's been so far around the team and in front of the media.
Consequently, the configuration was twitched, with the hosts switching to a back three comprising of Alderweireld at the heart. What was extremely alarming was how up Aurier saw himself plying his trade - almost as if his side were operating in a 3-2-5.
In reply, Chelsea continued to sit further back in their 5-4-1 defensive shape, and a distinct lack of incisiveness worked in their favour. Another aspect of the game that opened right up was the potentiality of Chelsea's counter-attacking chances.
Mount saw himself breaking away no lesser than three times, and on the overall note, the entire complexion of the match changed with the likes of Alli and Son drawing the opposition midfielders out of their boxes.
In what looked like a serious attempt to forge a comeback, Son raised his boot at Rudiger to receive his marching orders for violent conduct.
