Freddie Ljungberg enjoyed a winning Celtic debut in his side’s Scottish Cup victory at Berwick Rangers.
Daniel Majstorovic fired in a close range shot to give Neil Lennon’s side a 17th-minute lead at Shielfield Park.
But the visitors toiled for long spells on a bumpy pitch against spirited Third Division opponents.
Scott Brown fired in a neat angled strike on 81 minutes to ease Celtic into the fifth round of the tournament.
Former Arsenal and Sweden star Ljungberg has graced some of the world’s great stadiums, but the ramshackle Shielfield Park, with its bordering speedway track, was a distinctly low-key introduction to Scottish football.
However, the 3,877 packed inside the ground did their best to enjoy the occasion, making a din throughout a largely forgettable game.
