Neil Lennon will spend the international break attempting to solve his side's defensive problems – without the bulk of his players.
Saturday's dramatic 4-3 win over Aberdeen – recovering from being 3-1 down – was the second week running that the Hoops had lost three goals.
Despite that statistic Fraser Forster (England), Mikael Lustig (Sweden), Efe Ambrose (Nigeria) and Emilio Izaguirre (Honduras) will be away on World Cup duty before regrouping for Celtic's visit to St Mirren on Easter Sunday, leaving only Kelvin Wilson for Lennon to sort his defence with.
Celtic require seven points to retain the title and Lennon is determined to sort out his side's stuttering form.
"We have things to work on but I can't because I've only got four players to work with over the next two weeks," the Celtic boss explained.
