Wenger believes the value of these players has rocketed due to changes in recent seasons across European football.
"I believe it's because the density of players you have to fight against in the final third is always getting bigger, so the quality of the pass and the technique in that area has become much more important," he told the Official Arsenal Magazine.
"There is less space available, so accuracy is key. Secondly, because there is a smaller space the shorter players, the very agile players, are becoming more important and the taller players in midfield less so. That could be an explanation.
"It's changed in the last four or five years - the distances absorbed by players are becoming bigger and bigger, and therefore the limited space on the pitch demands more technical ability."
