I think you're wrong. Two people that I know have posted their info, and Bozza had a high Zamora rating which he then dropped down to low after something happened. Their input has been proved right in the past whereas I don't see your track record yet.
I'm going to hazard a guess, & it is only a guess, that he was going to sign, & then failed his medical.
The club are ethical so haven't broadcast that so it doesn't prejudice him going elsewhere. Pure speculation on my part.
