Arsenal produced another fightback as three goals in 17 minutes either side of half-time gave them a 3-1 victory at Leicester to prevent the Foxes moving second
  After two late goals earned them a dramatic Europa League win over Benfica in midweek, Arsenal had to come from behind again to earn three points at the King Power Stadium
Youri Tielemans put Leicester ahead (6) with a good finish into the bottom left corner, thanks to some wide-open, poor Arsenal defending, but the visitors levelled through David Luiz's clever header from a Willian free-kick (39)
VAR had earlier correctly denied Arsenal a penalty for Wilfred Ndidi's nudge on Pepe, just outside the box, but the two were involved again as Pepe's shot struck Ndidi's hand in the box, spotted by VAR, allowing Alexandre Lacazette to score from the spot (45+2)
Pepe extended Arsenal's lead with a simple close-range finish from Willian's centre (52), in a game where both sides felt the impact of Thursday's Europa League games as Emile Smith Rowe, Jonny Evans and Harvey Barnes all went off injured
The result means Leicester stay third, with Chelsea six points behind but with a game in hand, while Arsenal are back in in the top half
Leicester had won six of their seven Premier League games immediately following a European fixture this season, while Arsenal had lost six of their seven such games, and this contest was following that trend early on
After Leicester won the ball just inside Arsenal's half, Tielemans ran unopposed into the penalty area, with Jamie Vardy occupying the attention of Pablo Mari and Luiz on the left of the box, and struck into the bottom left corner from 12 yards
 It was a clinical finish from the Belgian, but Arsenal rolled out the red carpet with some woeful defending
Tielemans thought he'd given away a penalty just minutes later for a foul on Pepe, but VAR showed that it was in fact Ndidi's contact that brought the Arsenal man down, just outside the penalty area
Arsenal showed character to force their way back into the game - Pepe had the beating of full-back Thomas on the right, while Willian began to impress after receiving criticism recently for his performances - and they got their leveller with six minutes of the half remaining
After earning several free-kicks on the right flank, Arsenal finally got their delivery right, as Luiz peeled off the Leicester defence to latch onto Willian's square cross, heading into the bottom left corner past Kasper Schmeichel
Progress is rarely linear with Arsenal - Smith Rowe was forced off moments later with a groin injury - but they went into the half ahead thanks to another correct VAR call
 Pepe's shot was blocked by the outstretched arm of Ndidi in the box, initially not spotted before referee Paul Tierney and VAR David Coote intervened, before Lacazette converted from the spot
After Barnes was brought off on a stretcher with a worrying knee injury, Arsenal opened up a two-goal cushion early in the second half
Man-of-the-match Pepe fed sub Martin Odegaard, who slipped Willian in at an angle on the left byline, and his centre deflected off Tielemans and into the path of the waiting Pepe to turn home from a couple of yards out
Pepe has scored four goals in his last seven Premier League starts for Arsenal, as many as in his previous 21 starts in the competition combined, while Willian has now made more assists than any other Arsenal player this season with five
Evans was then brought off with another injury - only Crystal Palace (nine) have more current injuries than Brendan Rodgers' side (eight) - as Leicester struggled to get Vardy in the game to form a comeback of their own
Arsenal saw out the game professionally, with sub Pierre-Emerick Aubameyang firing just wide from the edge, showing their character and the benefit of rotation with a busy schedule ahead
Leicester, who were knocked out of the Europa League in midweek, now have a task on their hands to remain in the top half with a growing injury list, hoping to avoid the collapse of 2019/20 which saw them fall out of the Champions League places despite a large cushion at the end of winter
Leicester boss : On Barnes injury: "It's not good news, it looks like he needs to go in for an operation, so it will be a minimum of six weeks
 I believe it's around his cartilage
 He had a clash of knees a few weeks ago, so it has just been irritable
 Today he's had a challenge right on it, and it has just made it worse
"He'll need that repaired
 He's had niggles with it, that's why we tried to recover him on Thursday, but unfortunately it's a bad one for him, and a huge blow for us
"We're down to the bare bones, we've carried it all season and the players have been great
 It's absolutely fair enough
 My players to this point have been brilliant, but when you're missing the influential players and can't change, it makes it difficult
"Arsenal boss : "I am happy with the performance of the team, the character, composure we showed
 Coming here after a very short turnaround, and going down very early, but I think we showed really good moments, we were solid, and dominated the game, and overall deserved the win
"I think the team is clearly improving, taking a direction that I like - all the time I say the same: it's about consistency
 We are still giving things to the opponents, against Benfica and again today, and that's something we have to eradicate to give ourselves the best possible chance
