But it is the diminishing talent pool of young English players to succeed the likes of John Terry, Steven Gerrard and Frank Lampard that has been concerning Wilkinson most.
That match saw a change from the rigid 4-4-2 system previously favoured by Capello, and saw Barry used with Steven Gerrard and Frank Lampard in a central midfield triumvirate, with youngsters Adam Johnson and Theo Walcott employed on the flanks.
In Ferdinand's absence, Capello's captain on the field will be Liverpool midfielder Steven Gerrard, who is expected to partner Frank Lampard in the centre of midfield with Barry unavailable.
