Anyone sitting down to compile a list of last summer's best signings might want to start with the name of Guglielmo Vicario.
Tottenham seemed to be taking a chance on a goalkeeper from Empoli, who was beyond his mid-20s with no international honours and no experience of European football.
At £16.3million, Vicario signed from Empoli at about half the price of their initial target David Raya, and more than £30m less than Andre Onana, who joined Manchester United from Inter Milan.
Something about the deal seemed too good to be true. Where was the catch?
