McEachran will link up with his new team-mates in Portugal today and co-director of football Phil Giles revealed the midfielder had been on their radar for some time.
He said: "Josh is a player who our scouting team followed closely during the second half of last season.
“We quickly recommended him to Marinus, who of course knew Josh from his time in Dutch football and was quick to add his agreement to the discussion to proceed with the transfer.
