How old?
I'll hazard a guess this could work out perfectly.
A full stadium isn't like anything he would have experienced before and is pretty intimidating.
Getting a couple of games under his belt, getting familiar with the lay out and comfortable will help him settle.
Absolutely fudgingwell nailed on - the freaks.
If you're going to leave with 7 minutes of injury time, piling on the pressure and running the risk of missing the winning goal at the stadium opening.
Then proceed to leave on 80 minutes every single game thereafter, irrespective of kick off...
