You will not have heard of Etienne Camara before, but it is a clear statement of intent by Huddersfield Town

Who is he?

Etienne Camara is not a name you will have heard of before, but the signing of the aforementioned 17-year-old Frenchman is a clear statement of intent from Town.
Brahima Diarra and Loick Ayina were both signed after being spotted playing in the French Capital in October 2018, shortly after both of them became Town players but one player Town spotted in that trip proved hard to get - Etienne Camara. He came on trial at Town at the same time as both his compatriots did, but eventually, he signed for Angers - who he has just signed from.
Camara is a tall, left-footed central midfielder who is going to initially link up with Town's U19 squad. This season Camara had played once for Angers U19s, when they drew 1-1 with Championnat National U19s, with Etienne scoring Angers only goal. He signs a two year deal with Town, running to the end of 2022.

What does this mean for Town's transfer policy?

For me, signing lots of unknown quantities at 15-17 year old is the way the club should be going. Kian Harratt is a great example of this, Town picked Kian up from Leeds' academy and has been an integral part of the youth set up at Town. It is a much more sustainable model than what most teams use. The better the quality of the youth and reserve teams allows Town to not have to spend millions on bringing first-team players when they can be self-sustainable and promote players from within.
Other than Town I take a slight interest in Brentford, only because of the way they have their youth set up working. Brentford sign lots of young players, to develop for a profit. Town is sort of copying this idea to an extent and it is great to see.

Who do I see as Town's key prospects?

Luke Daley, Brahima Diarra, Jacob Chapman, Loick Ayina, Ilounga Pata, Robson Shipley, Patrick Jones and Kian Harratt are all showing positive signs of development. With all of these players being brought in under the same circumstances as Etienne Camara - any Football Manager fans know how good Luke Daley gets as well! As I have said before, I would much rather Town make more of these signings as it makes the Club more sustainable long term.
I have been critical of the way the club has handled their youth players in the past, Jordan Williams being let go for nothing while Duane Holmes being released, hopefully, Town is turning a corner.

Give Phil Hodgkinson credit!

The criticism that Phil Hodgkinson has received has been mostly justified, but his approach to the youth set up at Town has been spot on. Under the Cowleys, the football was old fashioned while also prioritising experienced players over anyone from the academy. This was proved by the players that he brought it, Andy King, Richard Steerman, Danny Simpson etc, while also referring to a 25-year-old Harry Toffolo as being 'young.'
The sacking of the brothers has allowed Phil to appoint a coach that has exactly the same ideology as the club, who prioritises youth development and has a direct link between the first team and reserves as seen by the introduction of the B team.
In my opinion this a copy of Brentford's model, but I don't blame him when Brentford have made nearly £100 million in players sales in the last 4 seasons, while only spending about £30 million.
