The most important thing for Wenger is for his teams to play football and be creative.
In 2006, I was asked to come and work at the club. I helped out Pat Rice when they did defending sessions.
There was one player who was making positional mistakes that were costing the team goals.
I wanted to flag up these mistakes to the player by showing him the footage but Wenger did not want him to see it.
In Wenger’s view, if a player sees himself making mistakes the problem becomes even bigger his mind.
That can be the case when you are discussing a technical aspect of a player’s game, such as passing.
But when the problem is positional and concerns a player’s body shape or angle of approach, it is worth going into detail and showing the player where he is going wrong.
I felt that by not addressing the situation, it would affect the player’s ability in the long term.
I don’t know whether things have changed now but Wenger is very protective of his players. He treats them like his sons.
But if players keep making the same mistakes, that will cost the team.
