Giving this some thought - those two sentences are irreconcilable.“I’m not going to tell him why he was subbed off at half time”
Next sentence
“I hope he picks up those points on why he was subbed off”
Might help if you told him then David you absolute beaut rather than leave him to guess.
Did he not mean that during the half time break he didn't tell him why he was subbed off. He told him why later and hope that he ( Tyler ) picks up on the reasoning?
That makes a lot more sense.
