BELGRADE (Reuters) - Former European Cup winners Celtic romped to a 5-0 home rout of Estonians Nomme Kalju in the first leg of their Champions League second qualifying round tie after forward Leigh Griffiths made an emotional return to action on Wednesday.

Red Star Belgrade, who won Europe's premier club competition in 1991, engineered a 2-0 home victory against HJK Helsinki thanks to a Richmond Boakye header and substitute Milan Pavkov's sweeping 90th-minute finish.
