Quite like the look of Tobe Leysen at OH Leuven as a GK signing. Would be more of a competition for Patterson signing than a outright no.1 though.
I think Petrovic and Bulka were amongst a small number of keepers, we could possibly recruit (ie within realistic terms) who would be a big improvement on Patto. Looking at transfermarkt (not the be all and end all), when you start moving down the list Patto's name pops up quite quickly. Not saying we can't improve on him, but it's becoming less likely we outright replace him and more likely we get another good option for him to compete with.
Good news for us if they flip him straight away and we have a sell on, as his value wont increase in Ligue 2
An observation with the Arokodore links is how few of the big number 9 players there seems to be around. Not that fashionable a style, I suppose, but surely it will always be effective.
