When I am 1 up at HT I dont say anything and it works more often than not. Which is weird in a way.
With team talks, its best to make notes what effects different players and use that to your advantage, but dont over use it - it doesnt become as effective then.
The one bad thing is that we as managers dont really 'know' a players personality - there is no real feedback, so we just have to make do with what we've got for now.
It would be better if 'Nothing specific noted' or suchlike is replaced with something else - does anyone know what this means anyway!?!?
Also, how does a player look delighted yet seems demotivated - had that a few times!
