Jamie Vardy continued his prolific season by scoring two goals - including a looping volley from 25 metres - to guide Leicester to a 2-0 win over Liverpool on Tuesday, preserving the team's three-point lead in the Premier League.
The England striker's stunning, long-distance strike put Leicester ahead in the 60th minute and he made it 18 goals for the season with a shot from close range in the 72nd after running onto Shinji Okazaki's deflected effort.

Sensational volley by the striker is quickly followed up by a second goal to bring Leicester a win over Liverpool.
After narrowly avoiding relegation last season, Leicester are providing the most unlikely title challenge in the 24-year history of the Premier League.
With 14 games left this campaign, Leicester are closing in on a Champions League qualification place and are now a definite title contender - especially if Vardy maintains his form.
Arsenal dropped five points behind Leicester after a goalless draw against Southampton.
Arsene Wenger's side found Southampton goalkeeper Fraser Forster in top form at Emirates Stadium and the north London side have now taken just three points in four games.
Southampton were the better team at the start and Arsenal goalkeeper Petr Cech had to tip James Ward-Prowse's free kick round the post.
Mesut Ozil missed a good chance for Arsenal when his close-range effort was pushed wide by Forster.
Forster also tipped Olivier Giroud's shot away before thwarting Theo Walcott and Alexis Sanchez.
Laurent Koscielny should have put the Gunners ahead after 70 minutes when Ozil found him in front of goal with Forster off his line but he headed over.
Manchester City kept their title challenge alive with a 1-0 away win against Sunderland while Tottenham Hotspur maintained their challenge for a Champions League spot with a 3-0 crushing of Norwich City at Carrow Road.
It was also a good evening for under-fire manager Louis Van Gaal as Manchester United, with goals from Jesse Lingard, Anthony Martial and skipper Wayne Rooney, scored a convincing 3-0 win over Stoke City at Old Trafford.
In London, second-half goals from Michail Antonio and Cheikhou Kouyate gave West Ham United a 2-0 win over 10-man Aston Villa that maintained the home club's push for European soccer next season and left their relegation-threatened Birmingham opponents looking increasingly forlorn.
Bournemouth eased their relegation fears with a vital 2-1 away win over Crystal Palace while Swansea held West Brom to a 1-1 draw.
