Ronnow ultimately stayed put, however, with Forest later turning to Watford shot-stopper Costel Pantilimon instead.
Palace, though, are arguably in greater need of reinforcements between the sticks, after Julian Speroni was potentially ruled out for the rest of the season through injury.
And the Eagles would be wise to muscle in on Forest's alleged pursuit, with youngster Dion-Curtis Henry stepping up as Wayne Hennessey's understudy.
Kapino is vastly more experienced than Henry, having made close to 100 senior appearances for Panathinaikos, 1.FSV Mainz 05 and Olympiacos - and has nine caps for Greece, for whom he made his debut at the age of 17.
That said, his links with the latter club - who released him at the end of last month - could leave Nottingham Forest in the driving seat, what with the two clubs sharing an owner in Evangelos Marinakis.
But would a move to Crystal Palace be more beneficial?
