This summer we signed 12 players, 6 of whom are English (Wright, Darling, Grimshaw, Moulden, Schlupp and Makama) which seems reasonably balanced. Last year we signed 14 players in the two windows, 6 of whom are English and 1 is from Northern Ireland. Of the others, Slimane and Marcondes both had previous experience of the English leagues, so the balance wasn't that bad.
IMO it was the overemphasis on youth last season that has caused problems, but that has been balanced somewhat now. I agree with Attanasio that young players need up to 3 years to develop fully, which is one reason current results need to be seen in a long-term perspective, which is why he says we are still in a three year process. The other factor is the injuries we've had. Attanasio is bringing in specialists to examine why our injuries are worse than every other team, but that will take time to make a difference, which is another reason for taking a longer perspective.
