It's not about being nice, it's about individual player management, which is fairly delicate with most youngsters. How often do players get subbed at half-time? It's basically the football equivalent of saying, "You're shit". If you give him an extra 15 minutes, he has the chance to improve and the manager still has plenty of time to change it.
Deschamps was so desperate to show Pogba and Griezmann that they hadn't done enough that he sent out the wrong side and ended up sacrificing another player to prove his point.
This entire post is precious.
Martial is a 20 year old man, not an 11 year old child, any decent player uses this to be more determined to do better next time.
I also thinking bringing someone off at HT is the football equivalent of saying, "You've had a tough half, it just hasn't worked for you, or us and we need to change something". Which is no doubt what the manager said to him,
"You're shit" would be leaving him at home or leaving him on the bench the entire tournament even when they are 1-0 down and desperate for a player like him.
Have any of you lot ever been in a football dressing room? Would you all have cried aged 20 when subbed?
