Striker Tammy Abraham scored his first goal of the Thomas Tuchel era as Chelsea set up an FA Cup last-eight meeting with Sheffield United.
Tammy Abraham scored his 12th goal of the season as Chelsea beat Barnsley 1-0 to reach the quarter-finals of the FA Cup.
Abraham tucked in his first goal of the Thomas Tuchel era in the second half and also headed off the line at the other end as the Blues knocked the Championship side out at Oakwell.
A young, fit Barnsley team gave a great account of themselves on a cold night in South Yorkshire, but it is Chelsea who will play Sheffield United in the last eight.
Chelsea have now won four and drawn one of their five games under Tuchel after he replaced Frank Lampard as head coach last month, and although they were not at their best, a much-changed Blues side had enough to edge through.
