Kewell came off the bench to score for Galatasaray in a comfortable 5-0 triumph over Estonian club Levadia Tallinn.

Abdul Kader Keita had earlier scored a first-half double and Milan Baros added a third from the spot in the second stanza before Kewell's strike.

Kewell struck on 78 minutes, when he collected a pass from Hakan Balta on the edge of the box before taking a touch and firing a low left-footed shot past Levadia keeper Martin Kaalma.

Galatasaray got a fifth, which reinforced their advantage ahead of the return-leg in Estonia, after a comical own goal from Levadia defender Vitali Leitan late in the game.

Elsewhere, Michael Petkovic's Turkish club Sivasspor continued their miserable campaign with a 3-0 home loss to last season's UEFA Cup winners Shakhtar Donetsk.

To make matters worse the Australian stopper was sent off late in the contest for a crude foul on Shakhtar forward Julius Aghahowa.

Earlier in the match, Petkovic had made a suspect decision on 7 minutes to offer the Ukrainians the opener, when he elected to block, rather than claim, a low-cross allowing Oleksiy Gai to slam home the subsequent rebound.

Sivasspor remained in the tie until late on, when a 76th minute long-range Ilsinho effort seemed to go under Petkovic and in to double Shakhtar's advantage, before Vasyl Kobin converted a nice team goal to add a third for the visitors.
