Mohamed Elyounoussi scored a 90th-minute winner to dig Celtic out of a hole and clinch an underwhelming 1-0 Europa League qualifying victory at Riga, securing a spot in the play-off round.

Neil Lennon's men were poor for long periods of the match, struggling to make the most of their superiority and undoubtedly greater quality, but substitute Elyounoussi finally found the breakthrough right at the end.

A collection of Riga fans in open-top buses behind one of the goals will not have been enough to intimidate Celtic, but the Scottish champions were significantly lacking invention for much of the game, managing only two shots on target in the first period.

Jeremie Frimpong, brought on for the injured James Forrest in the opening 45 minutes, showed some initiative and was unsurprisingly the one to craft Elyounoussi's goal, which secured a clash with either Sarajevo or Buducnost in the final qualifying round.
