'The Boys In Green' will air tomorrow night at 9.30PM, in honour of the passing of Jack Charlton.

The two-part documentary goes through Ireland's football fortunes, and how the national team managed to qualify for Euro '88 and, of course, the historic campaign in Italia '90 that led to the quarter-finals.

Directed by Ross Whitaker, the documentary features interviews with players from the team, including Steve Staunton, John Aldridge, Paul McGrath, David O'Leary, and Tony Cascarino.

The documentary details Charlton's career pre-Ireland, how he changed Ireland's strategy, how it eventually came to frustrate other teams, but more pointedly, how it produced results. The documentary was originally produced for the 30th anniversary of Ireland's qualification to Italia '90.

Here's a clip with Cascarino explaining how he came to be so good on the head.
