Dean Henderson strengthened his case to be Manchester United's number one with a brilliant save late on as Ole Gunnar Solskjaer's disjointed side beat Luton Town 3-0 in the EFL Cup.

United suffered a 3-1 home loss to Crystal Palace in their first Premier League game on Saturday and Solskjaer made 10 changes for the third-round tie at Kenilworth Road, including handing a debut to goalkeeper Henderson as David de Gea was given the night off.

A Juan Mata penalty on the stroke of half-time gave United the lead against their Championship hosts, who would have levelled with nine minutes remaining had Henderson's one-handed stop not denied Tom Lockyer.

By that point a concerned Solskjaer had called for the cavalry and substitutes Marcus Rashford and Mason Greenwood both added late goals for a victory that flattered United.
