Neil Warnock's new-look Leeds cruised past Shrewsbury in the first round of the Capital One Cup as goals from Luciano Becchio, Luke Varney, David Norris and Ross McCormack secured an easy 4-0 win.
Warnock named eight debutants, including Varney and Norris, and teenage defender Sam Byram, with the hosts taking the lead through Becchio in the 20th minute.
Another summer signing, Rodolph Austin, fired in a shot from outside the penalty area and, although Shrewsbury goalkeeper Chris Weale got down well to keep the ball out, Argentinian Becchio slid home the rebound from six yards.
Leeds doubled their advantage six minutes later following a sweeping move that ended with striker McCormack's shot blocked, allowing Varney to pounce and apply a neat finish.
Shrewsbury's Luke Summerfield lashed a shot wide for the visitors soon after, while team-mates Paul Parry and Jermaine Grandison had both gone close with long-distance efforts earlier.
But Leeds looked the more assured in possession and midfielder Norris twice went close to adding a third, before eventually slamming home a shot into the bottom corner from Varney's headed knockdown.
McCormack stroked his penalty into the bottom corner to make it 4-0 in the 70th minute after Shrews defender Michael Hector handled in the area.
