This weekend sees the fourth round of the FA Cup take place. There are lots of interesting ties taking place in the fourth round.

Among those ties non-league Macclesfield and Luton will be hoping to cause shocks against Premier League opposition.

Macclesfield host Premier League Wigan at Moss Rose. Mac defeated Championship high-fliers Cardiff in the third round and now face a home game against top flight strugglers Wigan.

The non-league side are in good form and have won three out of their last four games in all competitions.

The Latics are in poor form and have won just one game in their last four, that victory coming at League One Bournemouth in the last round of the cup. Roberto Martinez’s side needed a replay to dispose of Eddie Howe’s team. This game could be a banana skin for the Latics.

Luton face a trip to Norwich’s Carrow Road. Norwich’s form has been poor in the past few months and their only win in their last six games came at Championship Peterborough in the last round. The Canaries suffered a 5-0 defeat Liverpool in their last Premier League outing.

Non-league Luton have been inconsistent in recent months and have dropped down the Blue Square Premier League table to sixth. However in the last round the Hatters defeated Championship Wolves courtesy of an Alex Lawless goal.

Elsewhere, Premier League Reading host Sheffield United at the Madejski Stadium. The Royals have been in decent form and have won the last three games all competitions, including a 3-1 victory at Crawley in the last round.

Sheffield United are fifth in League Two after a slight dip in form of late. The Blades only victory in their last four games came at League Two Oxford in the last round. However, Danny Wilson’s side can’t be taken lightly.

Will there be any major shocks in the fourth round of the FA Cup?
