£4.5m. What would that get you in the upcoming January transfer window? A 34-year-old full-back who has made just one substitute appearance all season at West Ham? A goalkeeper you’ve never heard of from the Greek league? Well, obviously inflation is huge, but even in 1996, Gianfranco Zola was a bargain for Chelsea. In fact, in that year, the Stamford Bridge club could have bought, for example, one third of Alan Shearer, or three quarters of Nicky Barmby. He was a bargain of epic proportions and had a memorable career.
