Based on evidence, surely its Wenger? Even considering today's ridiculous inflation, majority of these players are vastly superior than the players going for much more today.
Imagine Bergkamp being available today for only £80m.
Sol Campbell = Free
Kolo Touré (£100,000) = £700,000 today.
Freddie Ljungberg (£3m) = £30m today.
Gilberto Silva (£5m) = £31m today.
Robert Pirès (£6m) = £46m today.
Patrick Vieira (£4m) = £47m today.
Laurén (£7m) = £50m today.
Marc Overmars (£6m) = £80m today.
Dennis Bergkamp (£7.5m) = £80m today.
José Antonio Reyes (£14m) = £95m today.
Thierry Henry (£11m) = £104m today.
