This weekend there are four Premier League sides who can be considered at risk of a major upset. With top-flight squads more stretched than ever before there’s every chance they take their eye off the ball in the cup, with plenty of willing EFL sides ready to take them down.

Brighton vs Blackpool

Giant Killing Index: 43 places between teams

Brighton just barely avoided a shock in the Third Round, when they needed penalties to stop League Two Newport. The Seagulls have struggled for victories throughout this campaign, so it wouldn’t be a shock to see them toil again this weekend.

Brighton head into this one with just two victories in their last 19 matches in all competitions, while they’ve only made it past the Fourth Round in two of their last six campaigns.

Meanwhile, Blackpool have pedigree as giant slayers. They took down Premier League West Brom in the Third Round. Since then they held league leaders Hull to a draw on the road, so we think they can make life difficult for the Seagulls and at least avoid defeat through 90 minutes here.

Sheffield United vs Plymouth

Giant Killing Index: 35 places between teams

It’s hard to trust Sheffield United with much at the minute. They survived a real scare against Bristol Rovers to progress from the Third Round, while they face another potential banana skin when they return to cup action this weekend.

Plymouth are coming into this clash in good form following three wins in their last four matches. Among those was a 3-2 victory at Huddersfield in the Third Round, just after the Terriers established themselves as one of the strongest home sides in the Championship.

Only time separates Sheffield United and the Championship at this point, so this isn’t too much of a stretch for Argyle. The visitors have lost only one of their last seven games and we’re backing them to hold out against Sheffield United too.

Brentford vs Leicester

Giant Killing Index: 20 places between teams

Everything is going perfectly for Leicester as it stands, but will that lead them to neglect the FA Cup? They aren’t far from returning to Europa League action and they’re in the Premier League title fight. That could see an under-strength Foxes suffer against proven top-flight troublemakers Brentford.

The Bees went all the way to the EFL Cup semis this term, with their defeat to Tottenham in that competition the only time they’ve failed to win in their last seven matches. The Bees had put out Southampton, West Brom, Fulham and Newcastle before falling just short to Spurs.

With Leicester distracted we think Brentford can pull off a result. The Bees last lost at home in early October, winning their last five here. We’re backing them to continue that streak this weekend.

Everton vs Sheffield Wednesday

Giant Killing Index: 36 places between teams

Sheffield Wednesday may sit second-bottom in the Championship, but a return of four wins and a draw from their last five has restored confidence for the Owls.

The visitors have also won four of their last five matches on the road in this competition, including last year’s upset at Brighton.

On the other hand, Everton have won one of their last seven FA Cup matches within 90 minutes. They drew at home to another struggling Championship side – Rotherham – in the Third Round before their extra time success. With Wednesday looking sharp they’re worth backing to frustrate the Toffees.
