Alexis Sanchez snatched all three points for Arsenal against Burnley on Sunday afternoon in the 98th minute, after some late, late penalty drama at both ends of the Emirates Stadium.

The Chilean superstar converted his last-gasp spot-kick to seal a 2-1 Premier League victory for the 10-man Gunners, who themselves conceded in injury-time, as well as having Granit Xhaka dismissed in the second-half.

Summer signing Shkodran Mustafi headed Arsene Wenger’s side in front shortly before the hour-mark, only for team-mate Francis Coquelin to foul Ashley Barnes in the 93rd minute, seeing Andre Gray fire his penalty past goalkeeper Petr Cech in what looked like an eventual equaliser.

But, after Wenger was sent to the stands for protesting referee Jon Moss’ decision, Clarets defender Ben Mee was penalised for a high foot on Laurent Koscielny in the box, before match winner Sanchez beat ‘keeper Tom Heaton with a Panenka-style penalty.

The hosts’ fifth league win in a row lifts Arsenal up to second spot, above rivals Tottenham and Liverpool, meanwhile Sean Dyche’s Burnley drop down to 13th, though they are still 10 points above the relegation zone.

Here’s three things that Shoot! learned from the Gunners’ dramatic win over the Clarets…

Xhaka will never learn

Wenger is still yet to resolve Xhaka’s disciplinary record, the Swiss international received his second red card of the season.

In November last year, Wenger stated that he was concerned about this, and said to ITV that Xhaka, “has to work on that and keep control of his reactions in the game.”

Xhaka will now sit on the sidelines for four matches due to his ban, missing the crucial tie against Chelsea on February 4.

The midfielder’s decision to dive in with a scissoring action gave referee Jon Moss no other option but to dismiss him.

His disciplinary record has now risen to nine red cards in the past three seasons, and this tally could rise if Wenger doesn’t resolve the issue, as the midfielder won’t get away with challenges such as this in the Premier League.

The problem Wenger now faces is a replacement for the next four games. With Mohamed Elneny away at the Africa Cup of Nations, Santi Cazorla still recovering from injury and Francis Coquelin’s lack of match fitness highlighted by his lazy kick to give away a penalty yesterday, Wenger seems to have a dilemma in the defensive midfield department.

Mustafi is absolutely crucial

Sunday’s victory, in which he scored his first league goal for the Gunners, marked Mustafi’s 15th consecutive Premier League game without defeat.

Arsenal have lost only three games this season – one coming on the opening day of the season against Liverpool, and two consecutive defeats in December against Manchester City and Everton.

Mustafi however was not involved in any of those three matches. He did not make his debut for the Gunners until a month after the 4-3 defeat to Arsenal, and was sidelined in December, recovering from a hamstring injury.

Cech can’t save penalties

Cech hasn’t saved a penalty for Arsenal in 14 attempts, including Andre Gray’s spot kick yesterday afternoon.

Any opposing penalty takers will feel comfortable facing Cech, knowing that as long as they hit the target they have a high chance of scoring.

A weakness in Cech is apparent. Through close analysis on each penalty, the penalty taker has sent Cech the wrong way on the last 12 spot kicks he has faced in the league.

Sanchez’s passion

At a time where players care more about the money rather than the game, Alexis Sanchez remains as fiercely motivated as ever to play every minute for his team and to try and win every game.

Sanchez never wants a rest. Wenger’s decision to not substitute him off on Sunday proved extremely beneficial, as his side clinched all three points late on.

He has a distinct passion to win, which is getting rarer in football.

As oddly as it sounds, the passion for winning a game of football seems to be slowly deteriorating from players in this current economic climate.

Sanchez showed against Burnley his passion to play and to win. All those spectating could see how much scoring the winning goal meant to him with his fiery celebration in front of the home fans.

Burnley’s atrocious away form

Burnley’s form away from home is the worst in the league this season, with just one point from a possible 30 so far.

Sean Dyche’s side need to up their game.

Even though they were unlucky not to scrape a draw after Koscielny’s penalty appeal should’ve been called offside, the Clarets have been abysmal on the road this season.

With 10 games played, Burnley have lost nine times, drawn once, scored four goals, but conceded twenty two.

This needs to be sorted out!
