Kai Havertz was the pick of the bunch for Chelsea during the international break, netting two goals against England at Wembley.
Graham Potter will no doubt have been watching the match, having previously been linked with the managerial role at England.
While Reece James assisted and Mason Mount grabbed a late goal from the bench, it was Havertz who impressed the most during the match.

And this performance could hand Potter the blueprint to get the best out of Havertz and Chelsea's underperforming attackers this season.
Thomas Tuchel utilised the German as a false nine during his time at Stamford Bridge, preferring him to club-record signing Romelu Lukaku last season.
However, it is clear that Havertz simply does not score enough to lead the line for a title challenging side which Chelsea aspire to be.

In addition to this, the arrival of Pierre-Emerick Aubameyang and Armando Broja being handed his chance in the Blues' squad this season will no doubt have an impact on Havertz's minutes at Stamford Bridge if he is to be considered as a number nine.
This role was something that the German admitted he did not mind playing, but we have seen Hansi Flick utilise him deeper in his Germany side, a team that look ever so impressive ahead of the World Cup.
Flick sees Havertz play as a second striker or a number 10, dropping deep to pick the ball up and act as more of a creative outlet.

Potter decided to name Havertz in a similar role in his only match, versus FC Salzburg, with Aubameyang preferred as an out-and-out striker.
The latest international break has shown promise for Chelsea's hero in Porto, with Havertz proving that he can also contribute with goals from deeper.
His opener was a brilliant strike after combining with former Blue Timo Werner before beating Nick Pope.
In Potter's system, Havertz could prove vital as an upgrade on Pascal Gross at Brighton, who played as a second striker and started the season on fire.

Havertz's creativity is one of the most underrated aspects of his game, but he has been unable to show it during his time at Chelsea.
Frank Lampard played the German as an eight during his first season at the club, stifling any attacking instinct, while Tuchel went for the polar opposite and threw him upfront.
The problem with the latter is that Havertz would be on the end of the chances, rather than creating them himself.

Chelsea have struggled for creativity in recent months, with Havertz often looking a frustrated figure upfront as he would struggle for chances and have to finish the one or two he got a game.
With him playing in behind a Aubamayeang, Havertz's role and responsibility changes and this will allow him to become the creative outlet of the Chelsea team, and also give him the space to run with the ball, take long shots and also contribute with hard-working defensive output as he has done previously.
It's now up to Potter to find a way to implement Havertz into his Chelsea side, but his performances during the international break have handed the English coach the perfect blueprint to implement him into his system at Stamford Bridge.
