Chelsea eventually broke the deadlock after 24 minutes when Alonso curled home a sublime free-kick from 25-yards out.
"The better team did not win the game".
Bakayoko is more mobile than Matic and was a useful midfield ball-carrier when Chelsea, starved of possession for long periods on Sunday, transitioned from defence to attack.
Chelsea boss Antonio Conte was a key reason in the Spaniard electing to move to England.
DF Antonio Rudiger, 6 - A hard afternoon for the new signing who found life tough up against Kane. Chelsea, sensing they had now weathered the storm, went even closer when Willian's low drive came back off the post with Frenchman Lloris beaten.
8 - It might have been obvious to play 3-5-2 and pack the central areas against Tottenham's powerful midfield and attack but it still worked exceptionally well.
A brace from Marcus Alonso, the victor two minutes from time, gave Chelsea a thrilling win over Spurs, whose tricky run, against them and at Wembley continues.
Marcos Alonso's free-kick gave Chelsea a 1-0 lead at Wembley. He contributed without the ball, too, making three interceptions, one tackle and three clearances throughout a successful debut. Last season we won the league and to win 30 games in the Premier League is not easy.
Pedro has assisted a goal in three of his past four Premier League substitute appearances for Chelsea.
He didn't make a telling impact on the game, but he was full of running as always and his energy and physicality were useful in Chelsea's bid to hold Spurs off. I chose to take the free kick and it went well.
MF Dele Alli, 6 - Created a couple of half chances but was kept quiet for most of the game by some tight marking. Spurs responded, but Thibaut Courtois blocked Harry Kane's speculative effort from 18-yards. Spurs kept on coming with wave after wave, but there was no way through.
"I am disappointed because we deserved more but they were very clinical with two shots on target and two goals", the 45-year-old Argentine told the BBC.
Mets trade Granderson to Dodgers
The 26-year-old Floro was claimed from the Chicago Cubs on August 4 and appeared in three games with Triple-A Oklahoma City. Joc Pederson has struggled at the plate, and while Yasiel Puig has been more good than bad in 2017, he remains mercurial.
Mauricio Pochettino may secretly echo Dorothy's sentiments in The Wizard of Oz.
Spurs continued to pile on the pressure with a succession of corners, but they were unable to seriously test Courtois.
Trippier got behind the Chelsea backline well five minutes later, but his centre was cut out with Kane lurking.
"It is nothing to do with the stadium", Spurs defender Ben Davies insisted after the game.
Pochettino made his first change with 22 minutes remaining, as Heung-min Son came on for the already booked Dier.
However, a disappointing 2-1 defeat to Chelsea on Sunday brought Tottenham back to earth. The players were clearly well-drilled and were constantly diligent in their efforts, pressing when possible and dropping off when required.
Jose Mourinho paid with his job before Christmas in 2015 as a squad in turmoil hovered improbably over the relegation zone but Antonio Conte's side allayed doubts over a similar implosion as they turned in a performance of grit and togetherness at the national stadium.
Bakayoko, who had been feeling the effects of not being quite match fit, conceded a free kick on the left.
Wembley was alive now and Tottenham scented a chance of claiming the scalp of the Premier League champions.
"That's the side more for left footers", Alonso said.
Conte went insane on the touchline and Pochettino showed his frustration, as his side had throw it away.
