Macheda set for Barnsley game

Manager Sir Alex Ferguson will ring the changes for this fourth round match with a Premier League fixture in mind on Saturday when they entertain Blackburn, while regular bench-warmer Brown will take on a big brother leadership role amongst what will be an inexperienced side.

Ferguson will hand a debut to Obertan, three months after the 20-year-old midfielder arrived from Bordeaux.

Obertan has proved his fitness following a back injury in three games for the reserves.

Danny Welbeck - who scored the winner against Wolves in the last round - Darron Gibson, Federico Macheda and the Da Silva brothers Rafael and Fabio could all be involved.
