Arsenal may sit top of the Premier League after 19 games, but Arsene Wenger's men don't lead every table at the halfway stage of the most unpredictable season ever.

From goals scored to average possession and distance covered, Sportsmail has looked at all the key numbers from this term to reveal the best - and worst - performers so far.

With both individual and team statistics, here's how your club and players have fared since August.

GOALS AND SHOTS

Watford's Odion Ighalo leads the way when it comes to shots at goal with 54, but it's Everton striker Romelu Lukaku and Leicester star Jamie Vardy who sit joint-top of the goalscoring chart, having hit the back of the net 15 times each this season.

Tottenham talisman Harry Kane is level with Ighalo for the most shots on target (32), while Foxes winger Riyad Mahrez is fourth for goals (13), eighth for shots (39) and fifth for shots on target (26).

Leicester and Manchester City both sit behind Arsenal in the Premier League table, but both teams have outscored the Gunners so far this term, grabbing 37 goals apiece in the opening 19 games.

Everton are the division's second-top scorers with an impressive 35 goals despite being 11th in the table, a return which leaves them ahead of Arsense Wenger's men (33), Tottenham (33) and West Ham (28).

At the other end of the table, Manchester United have managed just 22 goals this term - the same amount as Bournemouth and less than Watford (24), Crystal Palace (23) and struggling Chelsea (23). Aston Villa are the top-flight's lowest scorers with 15.

Everton are the Premier League's most prolific side when it comes to goals from open play (32), but the worst when it comes to converting set-pieces (three).

Title-chasing Manchester City fare well on both, having netted 28 times in open play and grabbed nine goals from set-pieces - almost double the return of Jurgen Klopp's Liverpool (five).

Palace and Spurs are the division's set-piece kings, with 11 goals apiece from corners, free-kicks and penalties so far this season.

GOALS CONCEDED

Sunderland are seven points adrift of safety so it's no real surprise that Sam Allardyce's men have the worst defensive record, having conceded 38 goals - four more than Bournemouth, Villa and rivals Newcastle United.

Tottenham have shipped only 15 goals this season - the lowest amount of any side - while Palace (16), Manchester United (16) and Arsenal (18) can also boast sturdy defences.

West Ham have made the most errors leading to goals (eight), with the season's surprise package, Leicester, having the league's lowest total (one).

GOALKEEPERS AND CLEAN SHEETS

Jack Butland has played a key role in Stoke's rise to the top half of the table, making a division-high 74 saves for Mark Hughes' in-form side and keeping out 79.57 per cent of the shots he has faced.

That return is second only to Palace stopper Alex McCarthy, who kept out a massive 80.56 per cent of the shots he faced during the opening six games of the campaign.

Butland is also joint top when it comes to clean sheets, having managed eight along with Watford's Heurelho Gomes, Arsenal No 1 Petr Cech and Manchester City keeper Joe Hart.

In terms of team clean sheets, no side has kept out the opposition more than Manchester United. Louis van Gaal's side have not conceded in 10 of their 19 games - two more than City, Arsenal, Watford and Stoke.

At the other end of the spectrum, rock bottom Villa and 15th-placed Norwich have each managed only two clean sheets so far this season.

PASSING AND POSSESSION

Bournemouth haven't abandoned their passing principles this season, with Andrew Surman showing some of the Premier League's more illustrious names how it's done.

The Cherries midfielder has completed the most passes (1,067) - 30 more than Arsenal star Santi Cazorla - and the ninth-highest amount in the opposition half (578).

Everton's Gareth Barry is third for successful passes (1,036), while Gunners playmaker Mesut Ozil tops the table for passes in the opposition half (783).

Wenger's stylish side also have the best pass accuracy (85 per cent), play the greatest percentage of short passes (91.2 per cent) and the lowest percentage of long passes (8.8 per cent).

Surprisingly, Leicester have completed fewer passes than any other side (4,325) and also have the worst pass accuracy at just 69.2 per cent.

While Arsenal top the passing statistics, no team has enjoyed more possession than Manchester United, who have averaged 60.8 per cent in their 19 fixtures so far.

Struggling Chelsea sit fourth in the table with 56.7 per cent, while Tony Pulis' West Brom are the only side who have control of the ball for less than 40 per cent of the game on average.

ASSISTS, CHANCES CREATED, CROSSES AND GOAL INVOLVEMENTS

Ozil has been the creative king of the Premier League this season, laying on an astonishing 16 assists - double the amount of Kevin De Bruyne - in 18 appearances.

The fleet-footed German has also created more chances than any other player (80), leaving him well ahead of his City counterpart (51) and Southampton's Dusan Tadic (50).

Ozil is joint second with Lukaku when it comes to goal involvements, having played a part in 19 goals this season - one less than Leicester star Mahrez.

TACKLES, INTERCEPTIONS, BLOCKS, FOULS CONCEDED AND FOULS WON

Stoke defender Erik Pieters leads the way when it comes to tackles this term, having challenged an opponent on 76 occasions - twice more than Leicester's midfield dynamo N'Golo Kante.

The former Caen man has made 11 more interceptions than any other player (77), while Swansea skipper Ashley Williams has made the most blocks (27).

Watford enforcer Etienne Capoue has committed the most fouls (36), while Southampton forward Sadio Mane has won more free-kicks than any other player (49).

DISTANCE COVERED AND SPRINTS

As well as being the Premier League's top passer, Surman has also covered more ground (230.7 km) than any other player since the season kicked-off in August.

Barry (225.4 km) and Surman's Bournemouth team-mate, Matt Ritchie (225.1 km), complete the top three, although the ex-Swindon winger is also third when it comes to sprints with 1,141.
