Sheffield United 2-0 Crewe Alexandra

Forward Ryan Flynn scored twice to put Sheffield United into the second round of the FA Cup after an ultimately comfortable replay win over Crewe.

Crewe's Callum Saunders should have scored only for Mark Howard to produce a fine save, and Flynn punished them soon after with a scrambled finish.

Brad Inman hit the post for the Alex before the break in a match in which they struggled to impose themselves.

Flynn sealed the victory with a quality strike after a Louis Reed through-ball.

Crewe can have few complaints having already had to rely on goalkeeper Ben Garratt to keep the deficit at just one goal, with the goalkeeper palming away Chris Basham's long-range effort and then tipping Stefan Scougall's header wide.

The Blades, who reached the semi-final before losing to Hull City at Wembley last season, will go on to face League Two side Plymouth Argyle in the next round.
