So what is your point? We incorrectly regarded Rossiter as a better prospect than Brannagan, but now we've come to our senses because Rossiter left to join Rangers and Brannagan is still in the reserves?
Is this some kind of wider point about UK scouting and coaching?
Well, I still like high energy, tough tackling midfielders. Players like Gerrard.
How is Brannagan still in the reserves? He made 11 first team appearances in the second half of the season. Klopp has raved about him, and now Barca and Real are interested. The indications are that we now probably do consider him as the best academy prospect.
As for the larger point, you mention Gerrard. He was a force of nature as an attacking midfielder, but never quite a great CM. Dele Alli and Barkley have similar qualities (obviously not as good). But if England try and shoe-horn them into central midfield like they did with Gerrard, they'll have similar results.
It stems from the idea that energy and tackling are more important in central midfield than passing, and I find that absurd. That's the logic behind Carrick having fewer caps than Hargreaves and Barry. Behind Scholes retiring at 30, while still bossing PL midfields for a decade after.
Also the logic behind the harebrained idea of replacing Alonso with Barry. Also the reasoning behind the idiots who said Mascherano was more important to us than Alonso.
This is all in the face of results as well - English teams were dominant in Europe in the last decade. Coincided with several outstanding midfields with a passer at the heart of them - Scholes, Alonso, Carrick, Essien, Fabregas, Petit, Modric etc. Even enforcers like Vieira and Keane were extremely patient and disciplined passers (unlike Gerrard).
That player had disappeared from England since the turn of this decade. I'm not surprised English teams have struggled in Europe since. There hasn't been a top class midfield in England with the ability to control the pace of the game for a while.
I'm really hopeful about Klopp bringing in a player like that - he brought through Sahin and Gundogan at Dortmund, and also signed Weigl (who's going to be a marvelous player).
I can see him being excited about Brannagan since he is a player in a similar mould (not saying that he will be as good as any of the players above - only commenting on the playing style).
Edit: I'm not refusing to acknowledge players like Kante and Mascherano, who've had great success in England as very defined role-players in midfield. Except if I were to construct my ideal midfield, I'd rather have a sitting DM like Makelele/Hamann alongside a passing playmaker.
