Pretty simple really.
Asking these players to keep the ball is retarded. If it's not something you do every single week then as soon as something goes wrong then the tendency is to change.
Obviously having technical players help, but even if you did it every week you'd see a big improvement.
Look at Swansea, it's not as if they have players with incredible technical all the way through the team, but if you get them doing it in training everyday and in matches even when you're losing then it will become natural.
