Walsh has a full scouting network.They know what he wants and is looking for.Walsh is at every home and away game with us.Which is why some questioned what he actually did as DoF. I trust him and his snidey little team to find us golden nuggets all over the planet.Moyes and Martinez were vastly more hands on, yes the process is still the same, the scouts find the players, in M&Ms case they probably went and had a look themselves, now its probably Steve Walsh going for a look while Ronny practices his backswing. I recall reading that Walsh makes funky little vids that he shows Koeman the players on and they make a decision based on that together.
