Antonio Conte will have been given plenty to think about ahead of Tottenham's next Premier League fixture - a trip to north London rivals Arsenal.
Both London rivals have made impressive starts to the season and the Gunners sit on top of the early Premier League table with 18 points from their seven matches so far, while Spurs are yet to lose a game and lie a point behind in third with 17 points to their name. The reigning champions Manchester City sit between the two London sides.
Mikel Arteta's men have received plenty of praise for their performances so far in this campaign, aside from their defeat at Manchester United. Whereas Conte's unbeaten side are widely seen as yet to have reached their top gear, despite scoring more than any other team in the league apart from City.

The Tottenham head coach has been tweaking his line-ups, using rotation with his multitude of attacking options in particular in between the club's Champions League and Premier League matches and that is only set to increase during a frantic fixture schedule after the current international break ends.
Teams must fit in a mass of Premier League, European and Carabao Cup fixtures before the long break for the winter World Cup begins. Spurs have 13 matches to squeeze in between October 1 and November 12, meaning a game every three to four days, which is going to test the squad.
That run begins with the trip to the Emirates Stadium and the events of Spurs' match at the weekend, the 6-2 victory against Leicester City might just have given Conte food for thought about another of his favoured systems.
Ahead of the match, the Italian was asked whether he had considered switching from a midfield two - which he has employed on the whole at Tottenham - to a three as he has used as other clubs in the past.
"I think we tried to sign a player [in Yves Bissouma] with the characteristics to play in a two. Then it happened during the game when sometimes we were winning to play with the three midfielders," said Conte. "In the past I've played with two strikers and three midfielders but this team when you have players like Sonny, Richarlison, Kulusevski and Kane, I think the best system we can play is [with two midfielders].
"We need only a bit of time to work with [Bissouma], for him to understand and to understand well. Now we have two reliable and important players in Hojbjerg, who for me he made important progress and now I think he's a really strong player. The same for Bentancur. Don't forget Skippy, who is really young. We're talking about a prospect but for me he's always been reliable and for this reason I count on him. It has to be very clear because for me Skippy is an important player as a midfielder, also gives me the opportunity to make rotation.
"For sure in the next 12 games, he can have a better physical condition and I can count on him also, Bissouma, Matthew [Doherty]. We need all the players in the squad because we have every game is massive. For this reason we need to have energy, energy, energy. If we think we have to play with the same players we're not going to have good results."
However, Bissouma's arrival on 70 minutes on Saturday transformed Tottenham's shape with a midfield three and unlocked the attacking ability of the side as Son Heung-min swept home a remarkable hat-trick in less than 14 minutes. Spurs controlled the midfield from the moment the Mail international joined the fray.
The Brighton man has been one of the best midfielders in the Premier League in recent years but Conte told football.london ahead of the weekend's game that the player had struggled to understand the tactical aspect of what was needed of him at Spurs in his early months, as well as needing to improve his defensive play.
However, in a midfield three against the Foxes Bissouma impressed, putting in his fair share of defensive work and after one perfectly-timed challenge in the Spurs box, it was another of his tackles in the hosts' half that set Pierre-Emile Hojbjerg away to tee up Son for his third and final goal.
Conte has said he prefers the 3-4-3 at Tottenham because it gets the best out of his attacking options and essentially he can fit more of them in.
However, with Dejan Kulusevski's ability to play as a right wing-back, there must be a temptation after seeing how Bentancur excelled in a three, Bissouma looked comfortable and Hojbjerg impressed, to go with a 3-5-2 at times with the Swede on the right. In that line-up Bissouma is replacing the more defensive full-back Emerson Royal and with a midfield three there is less pressure on the wing-backs to defend at times because of the extra man about to step back from the midfield to allow the back three to spread out.
Saturday's formation in those final 23 minutes or so also provided a timely reminder of just how potent Son and Harry Kane are as a partnership up front, without needing to be part of an attacking trident.
Against Arsenal in particular, playing just two midfielders within Arteta's packed centre of the pitch could be disastrous and the possibility of playing with all three central midfielders and Kulusevski on the right - the man sacrificed for Bissouma on Saturday - must be creeping into Conte's mind.
Injuries during the international break as players head off with their countries could also play their part but the thought of unleashing one of the Premier League's best in Bissouma with the safety net - in terms of knowing the Conte way - of Bentancur and Hojbjerg in a powerful midfield, surrounded by the creative wide men of Perisic and Kulusevski and the pairing of Son and Kane up front will be a very attractive one.
Conte told football.london that he believes he will be able to count on Yves Bissouma after this break. The north London derby might just be the first test of that theory.
