Also my son's season ticket just jumped up to £145 because he'll be 10 next season. That seems a bit steep but as usual I will end up paying it.
Your son's ticket has jumped up BY £145, or TO £145?
If it is the latter, as you've written, then his seat, at the Amex is going to cost £7.63 per Premier League match (or £6.30 per Championship match).
'Seems a bit steep'?
REALLY!?
