Celtic lost 1-0 to Legia Warsaw in their first pre-season friendly tonight.

Close-season signing Kenny Miller made his Celtic debut, as did Jiri Jarosik.

But it was Aiden McGeady and Nicky Riley who came closest to scoring.

McGeady had a first-half 'goal' disallowed for offside, and Riley forced a fine save from Jan Mucha from a header.

Stilian Petrov, who continues to seek a move away from Parkhead, also saw an effort well stopped - before David Marshall saved a Roger Guerreiro penalty, which had been given away by Thompson's mistimed tackle.
