The FA Cup returns this weekend and one match-up has really whet FootballFanCast's appetite; Sutton United vs. Leeds United, our Fixture in Focus, at 2pm on Sunday.

Indeed, there may be teams of higher quality involved in the Fourth Round but there's such a magical feel about this one: a non-league side with giant-killing-previous hosting one of English football's biggest clubs in an almost exact replica of their meeting 27 years ago - a 6-0 win for Don Revie's Whites that drew a 14,000 crowd to Gander Green Lane.

We're hoping the 90 minutes will be a little closer this time around, though, and there's certainly much less between the sides these days - in fact, Sutton reached their highest ranking throughout the English pyramid of 95th earlier this season, whilst Leeds - although on the march for promotion - obviously aren't dominating the top-flight in the same way they were under Revie.

Bearing that in mind and the old adage of FA Cup magic, Sunday's game could well come down to which side dominates the key individual battles.

SO, here are THREE that could decide the outcome of the Fourth Round clash.

Chris Wood vs. Ross Worner

It seems anything other than a resounding Leeds win will require some goalkeeping heroics from Sutton No.1 Ross Worner, a shot-stopper of decent pedigree having previously enjoyed short spells at Charlton Athletic, Aldershot, Woking and AFC Wimbledon.

That experience should give the 27-year-old some confidence heading into Sunday's game, but he faces a particularly tall (no pun intended) order in keeping 6ft. 3" Leeds front-man Chris Wood from getting on the scoresheet. The New Zealander has been in fantastic form to net 20 times across all competitions this season and enters the Gander Green Lane clash in hot form, following a run of six goals in his last four Championship appearances.

Matt Tubbs vs. Pontus Jansson

Many rate Pontus Jansson as Leeds United's top performer this season and certainly their smartest business of the summer, having established himself as one of the first names on the team-sheet since arriving from Torino on a season-long loan. His 6ft. 5" frame could prove pivotal in a game that may well be decided by set pieces - seemingly Sutton's best chance of finding the net - but at the other end of the pitch, he'll have to be wary of the predatory instincts of Matt Tubbs.

A regular goalscorer for Crawley, Bournemouth, Portsmouth and AFC Wimbledon in the Football League, Tubbs signed for Sutton at the start of December and grabbed his first goal in the second round of the FA Cup to eliminate Cheltenham, whilst his second was a late equaliser against Eastleigh last weekend.

Pablo Hernandez vs. Nicky Bailey

Since returning from injury, Pablo Hernandez has reclaimed his place at the tip of Leeds' midfield, pushing the prodigious Kemar Roofe out wide. In terms of natural talent, the former Valencia and Swansea City playmaker will be head and shoulders above the rest on Sunday, but if there's one Sutton star who can at least attempt to match him in terms of quality, it's 32-year-old Nicky Bailey.

Not exactly a household name, the tenacious midfielder, who will likely line up directly against Hernandez in a holding role, previously won Player of the Year awards at Barnet, Southend and Charlton Athletic and almost reached the Championship play-offs with Middlesbrough in 2012. More than simply a defensive presence, however, Bailey loves to find the net, notching up five in league action so far this term.
