Players from the Scottish league generally fall into the Latics' price range and Martinez feels the amount of game time youngsters get north of the border is also a massive bonus.
"Young players need to play football and they need to find experiences and find their way in football games," Martinez said.
"At the moment, a lot of youngsters for different reasons do that in the SPL in Scotland.
"I'm not saying that is all positive, because for the teams, they lose a lot of experience and it devalues the standard a little bit.
"But many youngsters there are allowed to make mistakes on a football pitch, and that is the only way you progress.
