There is no surprise in that, the just turned 23-year-old has not played competitively since the end of May and here is being thrown into one of the biggest games of the Premier League calendar.
Some may think that is a rash decision, but it was one that had to be made from the Italian as his hand was forced with the suspension to Cesc Fabregas.
To accommodate Bakayoko, Conte also changed his formation from the usual 3-4-3 to a 3-5-1-1, with David Luiz playing an anchor role in front of the three at the back.
Bakayoko ended up playing a little higher up the pitch than maybe Chelsea fans can expect to see the Frenchman play during his time with the Blues.
Within 30 seconds we saw a glimpse of what has been raved about in France when it comes to the midfielder, with a show of strength that will please Conte. He muscled Mousa Dembele off the ball to show Chelsea fans what they can expect.
His early battles seemed to be with the Belgian, with the pair going head to head several times through brute strength. To be fair to Dembele, he seemed to be matching his central midfield opposition like-for-like, probably being the stand out Spurs player on the pitch.
Everything we know about what Bakayoko is going to bring to this Chelsea team is power, fight and determination, something that should mould well with the obvious skills of Kante.
But in this formation, it was the fact we saw him higher up the pitch, often supporting Alvaro Morata. The Spaniard had a superb chance to score with a header that he should have guided on target, but instead fluffed his lines. But the man right next to him was Bakayoko, keen on getting on the end of a cross himself.
The 23-year-old is known for his big hits and tackling, and he certainly didn’t hold back when firing a header against Ben Davies and then a big hit on Victor Wanyama in the first half.
With Luiz patrolling behind him, Bakayoko was given a little respite from having to do so much running, which was no doubt of great relief to the summer signing.
It was Marcos Alonso that really had the moment of quality in the 24th minute when Luiz was brought down by Dele Alli. The Spaniard stepped up and curled a wonderful free-kick out the path of Hugo Lloris and into the top corner of the net.
His aerial ability will no doubt be a great asset to the Blues as well, showing that with important flicks away from corners and free-kicks, not afraid to throw himself at the ball.
When half-time came and went, you expected Bakayoko to be taken off, having played some of the friendly on Thursday against QPR and obviously showing some signs of fatigue.
However, as Alvaro Morata and Willian came off for Michy Batshuayi and Pedro, the minutes ticked away as Bakayoko tried to get himself around the pitch.
But if anything, the occasion spurred him on to put in even more energy. Conte said after the game: “Great motivation, great stadium, great opponent, great atmosphere. I think that brought him to an amazing performance.”
With the ball at his feet, he in truth provided little. With tired legs and a Spurs team nipping at his ankles at every chance, he struggled to make a massive impact on the game with influential passing or spraying the ball around.
You could see the legs going slightly, with a tired mind forcing him to make a silly error for Spurs’ free-kick that ledd to their goal in the 82nd minute. He bundled over Alli, with Christian Eriksen curling in the ball for Batshuayi to accidentally nod into his own net.
However, Bakayoko, Batshuayi and the Blues were let off the hook when Luiz dispatched Wanyama of the ball, fed it to Alonso and he rifled under Hugo Lloris for the winner.
All in all, Bakayoko’s debut was always going to be one to watch, rather than the finished article. The promising signs of what he can bring to Chelsea are obvious to see.
The fact he played 90 minutes is amazing, and he will no doubt get stronger and fitter and he will be all the better for a superb victory for the Blues.
