Millwall 3 Aldershot 0

Kenny Jackett's side will also enjoy home field advantage for the tie, which will take place on the weekend of January 3 and 4. The Millwall manager was hoping to be paired with a Premier League side, but his team will fancy their chances of progressing against one of two teams currently located in the bottom half of the table.

Crewe Alexandra - who will face Millwall in the league in three weeks - are rock bottom of League One, while Carlisle are in 17th following a late 1-0 defeat at the Den on Tuesday.

The Lions increased their run of clean sheets to five in the second round tie on Saturday, with Aldershot unable to provide a killer finish in front of goal. The spectre of the feared FA Cup upset never really emerged as a trio of headers allowed Millwall to power into the next round, but the scoreline was possibly a little harsh on the combative and well-organised visitors.

Striker Gary Alexander was on hand to nod home on 30 minutes after connecting with David Martin's well-placed cross. The conference side's best chance came on the hour mark, when keeper David Forde failed to grab a corner, leaving Tony Craig to clear the ball off the line from Chris Blackburn.

Kenny Jackett pushed Chris Hackett into a more attacking role on the hour mark, and it was his cross on 77 minutes that allowed Alexander to give Millwall a two-goal cushion. And he looped the ball in again two minutes from time for Ashley Grimes to give the scoreline an even rosier hue.

Alexander passed up a chance to complete his hat-trick deep into stoppage time, but he blasted his shot over after latching onto an Aldershot backpass.
