They also entered the UEFA Champions League directly at the group stage, as well as taking part in the two domestic cup competitions, the Scottish Cup and the Scottish League Cup.

To prepare for the Season, Celtic took part in two Pre-Season Tournaments; the Algarve Challenge Cup in Faro, Portugal, where they finished bottom, having faced Middlesbrough and Cardiff City, and the Feyenoord Jubilee Tournament in Rotterdam, where they finished second, having faced Tottenham Hotspur and host club Feyenoord.

The Championship flag was unfurled before Celtic's first League game, against St Mirren at Celtic Park on 10 August by Rosemary Burns, the widow of former Celtic player Tommy Burns, who had died of skin cancer at the end of season 2007–08. Celtic won the game 1–0, through a Barry Robson penalty, getting their Campaign off to a winning start.
