The Blues were made to work relentlessly in order to maintain their 100 percent record in the Premier League this season as the Magpies resorted to a tiresome "backs to the wall' approach from the start".
However, they came up against a stubborn and well-organised defence at St James' Park and struggled to break Newcastle down despite a dominance of possesion that bordered on the ridiculous. When you are Newcastle you have to manage because you are in the Premier League.
Asked if experienced players find his approach to defending scary, Sarri replied: "For two or three months. So yeah I think it's a penalty for Chelsea". "It is easier, for a defender who is 30, it is more hard".
"I like to be organised defensively, but now, again, I was watching teams yesterday playing 5-4-1 and it was said they are great tactician because someone has an opinion on TV". It depends on the vehicle you have, you have to drive that auto in the best way.
"Initially I thought it was a penalty, but when I saw it he [Schar] does get the ball".
'But we did work very well. "Maybe I have to do that [adapt my ideas], but I am better when I play my football, my way of football". Last season we were the best team in the bottom 10 and we hope to do the same again if we can.
'Possession is just for the TV, for the stats. On Sunday he was fouled five times - more than twice as much as any other player on the pitch - and Newcastle constantly had four or five defenders around him in an attempt to nullify his threat. The benches are on the line of the half, so for me it was really hard for me to say if it was a penalty, the same for the action on the other side.
However, the Brazilian now seems to be more settled under new boss Sarri as he bids to try and help the Blues enjoy a strong Premier League season.
"If you're a Newcastle player in that dressing room, you're embarrassed", said Harry's son - while former Reds legend Souness added: "I think you'd rather lose 3-0 having a go than lose the way they lost today".
