Leicester deserve huge respect for what they have achieved this season, and the Foxes will still occupy third position heading into Monday's clash at the King Power Stadium regardless of what happens on Sunday.
Indeed, a record of 15 wins, five draws and eight defeats from their 28 matches has left them with 50 points, but Brendan Rodgers's side are without a victory in their last four in the Premier League.
Not since a 4-1 success over West Ham United on January 22 have they triumphed in England's top flight, collecting just two points from the last 12 available, suffering successive defeats in the process.
Both Manchester City and Norwich City have beaten them 1-0 in their last two league outings, although the Foxes did manage to progress to the quarter-finals of the FA Cup with a 1-0 win over Birmingham City on Wednesday.
Leicester have also only won one of their last four meetings with Villa in all competitions and were knocked out of the EFL Cup in the semi-finals by their opponents in this match.
Saturday's results were kind for Villa as West Ham United, Watford, Norwich and Southampton all lost, while Brighton & Hove Albion were held to a goalless draw by Wolverhampton Wanderers.
Smith's team are still 19th in the table but are only two points from 16th-placed West Ham and would therefore move above the Hammers should they manage to triumph in this game.
It is also worth considering that Villa currently have two games in hand on the teams around them having been involved in the EFL Cup final against Manchester City last weekend, suffering a 2-1 loss.
The former Championship club have been beaten in their last three in the Premier League, though, losing to Bournemouth, Tottenham Hotspur and Southampton since the start of February.
Villa will face Chelsea, Liverpool and Manchester United in three of their four league matches after this one, meanwhile, which is an indication of the importance of Monday's clash.

Jamie Vardy has missed Leicester's last two matches with a calf problem, but the club's leading scorer should be available for Monday's contest having returned to training.
Wilfred Ndidi started against Birmingham having recovered from a knee injury and should again make the XI for this match, while Ayoze Perez and Harvey Barnes are expected to feature in the wide positions.
As for Villa, Tom Heaton, Wesley and Jed Steer remain on the sidelines, while the match will also come too soon for key midfielder John McGinn despite the Scot making progress in his recovery from an ankle injury.
Leicester possible starting lineup:
Schmeichel; Ricardo, Evans, Soyuncu, Chilwell; Perez, Praet, Ndidi, Maddison, Barnes; Vardy
Aston Villa possible starting lineup:
Reina; Guilbert, Engels, Mings, Targett; Nakamba, Luiz; Trezeguet, Grealish, El Ghazi; Samatta
We say: Leicester 2-1 Aston Villa
Leicester's form has not exactly been terrific in recent weeks, but the Foxes are due a win. Villa played well against Man City in the EFL Cup final but have the second-worst away record in the Premier League this season. As a result, we are finding it hard to back against the hosts, who should have enough to triumph.
