At the time, he was our record signing. We have bought more expensive players since, as BG said. He still remains our most expensive GK though.
Ryan WAS reported in the media as our 'record signing' with the 'undisclosed' fee being reported variously between £3.5m and €5.3m.
The club have since contradicted that though. In their transfer round up of the window, they clearly state that the club's transfer record was broken TWICE during the window (which would mean Propper and Izquierdo), thus suggesting that Ryan's fee was lower than the (undisclosed but reported between £2.6m and £3.2m) fee paid for Shane Duffy.
