I doubt you're in serious need of help but I'm sure you're wondering about others. Any u21 coach needs to contact every person who has a u21/NT potential player on their roster. I'll provide whatever support is necessary, though as I think I've made clear many times, players belong to their clubs and club owners are free to do whatever they like with them. I won't pester anyone but where support is wanted, it will be given.
I'm a defensive minded coach and I do have certain opinions on what skills should be trained. In most cases all players should be well rounded, I don't want to see one dimensional players, they're not very useful. Bigs need OD, guards need ID. All players need to be able to handle the ball. Passing is important. Obviously SB is the most important skill for a big man.
I have a history of training rounded players. Fallon, my NT player being a perfect example. 128tsp for less than 70k salary. High tsp is much more important than gaudy salaries. This would be better for the u21s/NT and better for the clubs.
No free body massages. No restaurant vouchers. If that's the kind of thing you want for training an England player you're in the wrong place. I doubt Sam Allardyce is buying Mourinho dinner. Though of course Mourinho doesn't train players.
