On average (and this is widely available info on the internet), clubs retain between 7% and 15% of shirt sales, with the remainder going to the manufacturer (ie New Balance).
So let's be optimistic and say we keep 15%. Now I don't know how many shirt sales we'd make, but let's say 10,000.
Ł55 a shirt. 10,000 sales. 15%. That's Ł82,500.
And that's assuming all those shirts are adult prices, and we've negotiated a stonker of a deal with NB. I also assume Ramsey would only be interested in shirts with his name on, too.
This deal may well have fallen on its arse but there's absolutely no way in the world that it's anything to do with shirt sales. Absolute nonsense.
