Tony Mowbray has been appointed Celtic manager, the club have confirmed.
The former West Brom manager will bring assistant Mark Venus and first-team coach Peter Grant, a former Celtic team-mate, with him to Parkhead and current Hoops coach Neil Lennon will also join the new management team.
Mowbray will meet the media at a press conference at Celtic Park tomorrow morning.
Mowbray's appointment finally brings to an end weeks of speculation about who would succeed Gordon Strachan, who departed after failing to win his fourth Clydesdale Bank Premier League title in succession.
West Brom chairman Jeremy Peace reluctantly agreed to allow the Glasgow giants to speak to Mowbray on Saturday after Celtic agreed to pay £2m in compensation for the former Parkhead defender.
After Mowbray agreed personal terms, and compensation had been agreed for Venus and Grant, Celtic announced on their official website that the deal had been completed although there were no details of his contract or of what role Lennon will fulfil.
Lennon, who was part of Strachan's coaching team, was promised a role at Parkhead for next season by Celtic chief executive Peter Lawwell.
There has been speculation that Lennon would take over as reserve team coach from Willie McStay, but his job will become clearer at tomorrow's press conference.
Mowbray's first job will be to assess his squad ahead of the first of possibly two tricky Champions League qualifiers at the end of July.
With the Clydesdale Bank Premier League fixtures being announced tomorrow, Mowbray will discover who will be his first opponents in the league campaign.
Mowbray will need no introduction to Hoops midfielder Scott Brown, midfielder Gary Caldwell and striker Chris Killen, all of whom were under his charge when he was Hibernian boss.
However, Mowbray will have to address several areas in the side and has already been linked with numerous players including Baggies captain Paul Robinson, Nancy striker Marc-Antoine Fortune, Iceland international Hermann Hreidarsson and Sweden Under-21 skipper Mattias Bjarsmyr.
