OPINION: Premier League: Five talking points
1. When will Leicester City's bubble burst?
I am sure not many would have predicted that Leicester City would top the Premier League table after 13 games. Not even the most ardent of Leicester fans would have predicted this.
The initially perplexing appointment of Claudio Ranieri to replace Nigel Pearson is now an inspired choice.
His team on the pitch is reflecting the 'Tinkerman's' easygoing nature. Leicester are devilishly dangerous on the counterattack, their inspired run this season led by Jamie Vardy has seen them lose only once (to Arsenal) in the Premier League this season.
However, Leicester's litmus test comes at a crucial stage of the season.
Their next six fixtures include the likes of Manchester United, Chelsea, Everton, Liverpool and Man City.
Surely this wonderful underdog story will slowly fade before the end of the year.
Although many neutral fans will be wishing it continued, as Leicester have some fine individual talents that are easy on the eye.
Ranieri, so often written off because of previous managerial stints, would be forgiven if he was smiling smugly at those who doubted his abilities.
2. Manchester United continue grinding out results
United won their encounter 2-1 thanks to a stoppage time after Troy Deeney's own goal a few minutes after the striker had hit the equaliser from the penalty spot.
United was wasteful in front of goal, but also have David De Gea's defiance in goal to thank.
They edged Watford in the possession and goal attempts in the match and arguably deserved the win, but made it difficult for themselves.
Memphis Depay returned to the starting line up with a goal in the 11th minute after a sumptuous Ander Herrera cross.
Thereafter, United controlled the game missing numerous chances with a few special De Gea saves littered in between.
A tired challenge by substitute Marcus Rojo allowed Watford to equalise from a penalty. This, however, stung United into action.
Their reaction to Watford's goal had shades of 'Fergie Time' about it as United secured the win in stoppage time.
United now sit second on the table with their fixture next week against Leicester City, atop of the table clash with only one point separating the two.
In another sub plot to match, Jamie Vardy will look to secure the record of scoring in the most consecutive Premier league matches. He currently shares the record of 10 games with former United goal scoring machine Ruud Van Nistelrooy.
3. Liverpool shine, Manchester City falter
Liverpool's high pressing defence in the first half overwhelmed City with the 'Klop Effect' seemingly on full display at the Etihad on Saturday.
The Reds ran riot, embarrassing City 4-1 at home. Liverpool never allowed City to settle on the ball, added to this the fact they looked composed on attack and very dangerous on the counter.
Klopp's fluid formation allowed Firmino and Coutinho and at stages Lallana to cause havoc for the home side's defence, producing some beautiful passing movements on course to creating a number of chances on the day.
Many of those chances went unpunished or were halted by Joe Hart. Liverpool has a tough Europa League clash against Bordeaux on Thursday before they take on Swansea next weekend. They will hope to carry the momentum this win has given them.
City, on the other hand, were a serious letdown, they missed an opportunity to consolidate top spot on the table for themselves.
Pellegrini might regret leaving Nicolas Otamendi on the bench as centre back pairing of Martin De Michelis and Eliaquim Mangala were exposed by the enterprising Liverpool attack. Yaya Toure and Fernando were also overrun in the midfield, especially by Emre Can. Pellegrini's decision to leave out Fernandinho could also be called into question.
It certainly does not get easier for City, as they take on Juventus midweek before squaring up against a very capable Southampton side at the Etihad.
4. Chelsea hope to kick start their dismal season
Back to normal for Chelsea, they snapped a three-game losing streak in the Premier League to beat Norwich 1-0 at Stamford Bridge.
Mourinho got his customary clean sheet and home win, Hazard dazzled and showed why he was the player of the year last season and Diego Costa got back to scoring ways. Chelsea are still only 15th on the table, closer to the relegation zone than fourth place, this indicates that there is still a mountain to climb to assemble some respectability from this season but this win is a start for the champions.
The most encouraging take out for Chelsea was the form of Hazard, he operated 'in the 'no. 10' position in the match.
Hazard took on defenders, gliding past some with ease and twisting and turning his way to a total of nine dribbles in the match. Diego Costa also ended his seven game goal drought, which eases the pressure on the striker whose goals were so crucial last season.
Another risk which paid off for Mourinho was his decision to start 19-year-old Brazilian Kenedy at left back in place of the reliable Cesar Azpilicueta.
The youngster was a success on defence and attack; his lightning pace gives Chelsea more of an edge going forward than the right footed Azpilicueta. Chelsea could yet stumble next week when they take on the impressive Spurs at White Hart Lane.
5. Is this Spurs team the real deal?
Spurs have flattered to deceive in the past, so one must be cautious not too get carried away when discussing Spurs' top four ambitions.
You cannot ignore the fact that this team has not lost a match in the league since their opening day defeat against United courtesy of an own goal.
Spurs were sublime on Sunday dismantling city rivals West Ham 4-1 at White Hart Lane, the win puts them four points of the top now. Harry Kane continued his good form, scoring two, which makes it four consecutive league games in which he has scored.
Spurs also have the youngest Premier League side on average, their youthfulness can be witnessed from their high intensity game. The most impressive aspect of this young team is how hard they are to breakdown defensively. Spurs have conceded only 11 goals this season, tied second behind Man United for the best defensive record.
The signing of Toby Aldeweireld was shrewd but Mauricio Pocchettino's decision to play Eric Dier as a shield for the back four has been a masterstroke. Dier has formed an exciting central midfield partnership with Dele Alli.
Spurs face Chelsea next week in another London derby; a win could see them make their way into the Champions League spots. This should serve as enough motivation for this young and ambitious team.
