Celtic have agreed to allow Paul Lambert to begin a coaching course with the German Football Association.
Paul Lambert wants to go into coaching
The ex-Scotland skipper, who enjoyed a spell at Borussia Dortmund, is set to spend two four-week periods in Germany.
The 34-year-old will miss the start of the new campaign and hopes to move into coaching when his Celtic contract expires next summer.
Lambert's agent, Gordon Smith, told the Sunday Mirror: "Celtic appreciate the prestige that comes with this course."
Smith continued: "Paul is the only non-German involved in the course and the Germans are very pleased to have him with them.
"Part of it requires him to work on youth development and, when he is in Glasgow, he will be working and studying alongside the Celtic youth coaches.
"Paul has already started work on the course and was over at the European Under-21 championships in Germany at the start of the month.
"Martin O'Neill appreciates how important this is for Paul and has been very co-operative and helpful."
