Wild spending increasing across Premier League primarily (9)

'wild spending' is the definition.
The definition and answer can be both to do with ownership as well as being present participle verbs.
Maybe there's a link between them I don't understand?

'increasing across premier league primarily' is the wordplay.
'increasing' becomes 'surging' (I am not sure about this - if you are sure you should believe this answer much more).
'across' indicates putting letters inside.
'primarily' says to take the initial letters.
The initial letters of 'premier league' is 'pl'.
'surging' enclosing 'pl' is 'SPLURGING'.
