If you're talking about a player's success being inflated by penalties, 23 of Toney's 68 goals for Brentford have come from them, and 11 out of 32 in the Premier League. Far more heavily weighted than Vlahovic's 12 from 49 goals for Fiorentina.
Thankfully I don't think we'll go there but signing Toney would be symptomatic of the problems we've had for the last decade. A 28 year old (by the time he's next available) unproven at the very top level with a reliance on penalties to prop up his goalscoring numbers. No chance Brentford sell him cheap either. We need to be far more careful with how we use our resources.
