Jez is supposed to be the arch negotiator, apparently it's his major strength although he hasn't really got us that many brilliant deals on fees, Jarvis/Fletcher were about market value given how they'd played for us in the Premier League (notwithstanding that neither proved their worth at their next club), Camara was good money in the end given the loan fees from Celtic and Southampton and Olofinjana was daylight robbery on our part. In Jez's time we've also managed to lose Rae, Miller and Sako for nothing and got bullied into sales on Kightly/Davies due to contracts winding down which isn't great for a club which apparently prides itself on having a handle on that kind of thing.
He managed to get £5m for Lescott. Now given that Joleon was a) older b) had serious injury concerns hovering over him at the time and c) that was 10 years ago, in which time the Premier League TV revenues have increased four or fivefold, I would be seriously pissed off if we only got around that much for Iorfa now.
