Leeds United are into the third round of the Carabao Cup after claiming a 3-1 win over Barnsley.
With 25 minutes gone, summer signing Luis Sinisterra scored from 25 yards to put the home side ahead.
Elland Road was rocking again before half-time when Mateusz Klich converted a penalty.
Barnsley pulled one back through Mads Andersen's diving header.
The League One side then missed a penalty as Callum Styles could only hit the post.
Klich grabbed his second of the game early in the first-half to seal victory for Leeds.
