Leicester's lead over Spurs, Arsenal, City is tightest Premier League battle
Leicester City may now be favourites to secure a shock Premier League title success but the Foxes cannot rest on their laurels.
The gap of six points separating the top four in the table would be the smallest in the competition's history should it remain unchanged, with Tottenham, Arsenal and Manchester City also eyeing the top prize.
Claudio Ranieri's Leicester have lost just twice this season and are five points clear at the summit -- but face a tricky trip to the third-placed Gunners on Sunday.
Spurs and City meet later in the afternoon on a day that could see the distance grow to nine points but, whatever happens, with the nature of this season's league it is likely to remain a tight race.
Here, Press Association Sport takes a look at some of the previous battles between the league's top four.
1996-97 -- Champions: Manchester United (75 points), fourth place: Liverpool (68)
Sir Alex Ferguson's Red Devils won a fourth title in five years with what remains the lowest points total for Premier League champions.
They saw off Newcastle, Arsenal and Liverpool, who all finished tied on 68 points -- meaning a gap of seven points between top and fourth, still the equal-smallest in the Premier League era.
2004-05 -- Champions: Chelsea (95 points), fourth place: Everton (61)
While seven points is the smallest gap, Jose Mourinho's Blues opened up a yawning chasm of 34 points to fourth-placed Everton as they cantered to the title in 2005.
Their 95 points is the highest haul in the Premier League while the Toffees' 61 would not have been enough to reach the top four in any season since.
2013-14 -- Champions: Manchester City (86 points), fourth place: Arsenal (79 points)
Another seven-point gap between the league's four best sides, with City this time taking the title after overtaking Liverpool who were five points clear with three games remaining.
The Reds finished two points behind, with London rivals Chelsea and Arsenal rounding out the top four.
2015-16 (with 13 games remaining) -- League leaders: Leicester (53 points), fourth place: Manchester City (47 points)
The current gap of six points is on course to be the smallest in the Premier League era as Leicester continue to lead the way.
While only six points cover Leicester, Tottenham, Arsenal and City, the Foxes are five points clear at the summit heading to Emirates Stadium on Sunday.
