Spurs responded swiftly through Dele Alli's header before they were the beneficiaries of a decision that left Guardiola raging and paved the way for the visitors to scramble a point. Referee Andre Marriner ignored Kyle Walker's push on Sterling as he raced into the area - and seconds later Son swept a low finish past City keeper Claudio Bravo with 13 minutes left. City pressed for a winner but were frustrated once more when Brazilian teenager Gabriel Jesus, on as for his debut as a substitute for Sterling, saw an effort ruled out for offside.
The result means Man City remain fifth, three points off second-place Tottenham and nine away from leaders Chelsea, who play Hull City on Sunday. City boss Guardiola will have few complaints about the manner of their performance but they were let down by the familiar failing of a lack of ruthlessness in front of goal. City played with verve and intensity as they penned Spurs back, but Sergio Aguero was frustrated on several occasions by Lloris, Pablo Zabaleta shot inches wide, Sterling missed that vital opportunity after he was fouled. New boy Jesus also headed inches wide.
Guardiola's animated body language spoke of his frustration - but there was also fury at the key incident - Sterling was shoved by Walker in the area seconds before Spurs attacked for Son to equalise. He had every right to be angry. City deserved victory and for all the justified criticism aimed in their direction, there was not too much wrong with this performance. Manchester City's Bravo provided the pre-match narrative with his growing reputation as the goalkeeper who rarely makes a save - but it was the man regarded as one of Europe's finest who was almost the real villain of the piece here.
Bravo was again the goalkeeping bystander as he extended his miserable recent sequence, but Tottenham's Lloris suffered a rare nightmare display and takes responsibility for both City goals. He should have done better than head a routine long ball against Sane for the opener, while his fumble that led to De Bruyne's second was the sort of work he would normally complete without a second thought. Bravo was powerless for the Spurs goals - although today's two goals make it 16 from the last 24 attempts on target against him - but Lloris' misfortune was proof of how matches, and the the reputation of even the best goalkeepers, can be decided by the finest margins.
Lloris has saved Spurs on many occasions but today he was saved by his colleagues. Mauricio Pochettino's side would not put this display anywhere near the top of any list of their best performances this season - but they may come to regard this as a priceless point earned without playing well. Spurs were over-run for much of the game, unsettled in possession by the pressure applied by City, but showed resilience and determination to get a draw they barely deserved. They were also grateful for City's generosity in front of goal as they wasted as succession of chances, and to referee Marriner for refusing what appeared to be a clear penalty when Walker shoved Sterling as he raced clear in what proved to be a decisive moment. Spurs' travelling fans celebrated as if this was a victory at the final whistle. Some days you just take the point and get home - to be able to do that at the home of close rivals will make it taste even sweeter.
