Wrexham had their opportunity, when they were at home and in front against Sheffield United's 10 men deep in stoppage time. It was all there for them but they could not manage the Hollywood finish to hold on and set up a fifth-round tie with Tottenham.

Chris Sutton's FA Cup replay predictionsIpswich, Sheffield Wednesday, Grimsby and Wrexham are just some of the lower-league - or non-league - sides still dreaming of FA Cup glory, but will they make it to round five where some big clubs await? BBC Sport's football expert Chris Sutton has cast his eye on this week's fourth-round replays, and picked out the teams he thinks will make it through to the last 16.
Sutton's prediction: 0-1Grimsby v LutonLive commentary on BBC Radio 5 LiveLeague Two (16th)vChampionship (4th)Who did they beat? 3R: Burton (L1) H3R: Wigan (C) Ar2R: Cambridge Utd (L1) A1R: Plymouth (L1) HThis one surprised me, with Grimsby getting a 2-2 draw at Kenilworth Road a few days after being smashed 5-0 by Swindon in League Two. Luton's level of performance was awful for a team in the Championship play-offs, and Grimsby might even have won it first time around - so they will certainly fancy their chances on their own patch. I don't see Luton being as bad again, though.

But both teams made so many changes when they first met that it made it incredibly difficult to predict what would happen. I can definitely see Ipswich manager Kieran McKenna doing the same again on Tuesday, and why wouldn't he? It's a long way for them to travel to Turf Moor and they play League One leaders Sheffield Wednesday on Saturday.
On top of that, Burnley's home record this season is almost impeccable, with 11 wins and four draws from 15 games in the Championship. It's going to be a long journey home for Ipswich fans, and I think it is going to be a miserable one. Sutton's prediction: 5-0Fleetwood v Sheffield WednesdayLeague One (17th)vLeague One (1st)Who did they beat? 3R: QPR (C) H3R: Newcastle (PL) H2R: Ebbsfleet (NL) A2R: Mansfield (L2) H1R: Oxford City (NL) H1R: Morecambe (L1) HPromotion is clearly the priority for Sheffield Wednesday. They have been on a great run to go top of League One, but they still have to watch out for teams like Derby who are giving it a real go to catch them. Fleetwood got a really good draw at Hillsborough first time out, and you might think home advantage gives them the edge now, but I actually think Wednesday will nick this one.
Everyone is talking about how exciting that game would be for the Welsh side but they are wrong to ignore Sheffield United after their form this season. Even if the Blades make more changes, they should win at home and make plans for when Spurs are in town in a couple of weeks. Sutton's Prediction: 5-1WEDNESDAY, 8 FEBRUARYSunderland v FulhamLive on BBC One, BBC iPlayer and the BBC Sport website, plus commentary on BBC Radio 5 LiveChampionship (9th)vPremier League (8th)Who did they beat? 3R: Shrewsbury (L1) A3R: Hull City (C) AWhat a story it would have been if Sunderland's 15-year-old midfielder Chris Rigg had not seen his late winner ruled out in the first game - he would have become the youngest-ever goalscorer in the FA Cup.
It was unfortunate for him, and for Sunderland too because they actually had a real go at Fulham. If the Black Cats win this replay they face Leeds, and we get a replay of one of the most famous FA Cup finals in history - from 50 years ago in 1973 when Sunderland goalkeeper Jim Montgomery helped the Second Division side clinch a brilliant victory and Bob Stokoe ran on the pitch to celebrate. But it is a big blow for them that striker Ross Stewart is out for the season with an Achilles injury, and Fulham still have to be favourites to progress despite being the away side. I think Marco Silva's side should look at the FA Cup as being a real opportunity for them this season, because they are not going to get relegated now - they have not reached the semi-finals since 2002, so why not aim for Wembley?
