Steve Morison and Russell Martin have been the main men for Norwich City over the first part of the Premier League season.

Paul Lambert's squad ethos has helped City to confound many of the pre-season predictions to sit inside the top 10 ahead of Saturday's latest test at West Brom – but Morison and Martin are the stand-out performers based on the league's official statistics.

Morison's matchwinner at QPR in Norwich's last league outing moved him back inside the overall top 40, predictably dominated by players from the title-challenging clubs. Manchester United and England forward Wayne Rooney currently heads the EA SPORTS Player Performance Index, which measures a player's all round contribution to the team. Rooney has amassed a score of 442 on the index from his 17 Premier League outings this season – 15 points clear of nearest rival and league top scorer Robin van Persie. Emmanuel Adebayor (409), David Silva (378) and Nani (360) make up the rest of the top five in the main list. City's top gun Morison is currently ranked at number 38 with a score of 242 after plundering seven league goals for the club in his debut season in the top flight – down seven places from his seasonal-high position of number 31.

Team mate Martin (223 points) is the nearest Norwich player to Morison, situated just outside the top 50 in 53rd place overall. The 26-year-old has been one of Lambert's most consistent performers following his switch into central defence prior to the recent returns of Zak Whitbread and Dani Ayala from long term injury.

Martin's form also earned him a recall to the Scotland international set up for the recent friendly in Cyprus before he was forced to withdraw with an ankle problem picked up in the away defeat at Aston Villa.

Grant Holt (63rd) and Marc Tierney (70th) are the other two City players inside the top 100 that ranks some of the best players in world football.

John Ruddy is the rated 12th on the goalkeeper ratings (162 points) with Manchester City's Joe Hart underlining his reputation as England's number one at the head of affairs (267 points).

The Canaries' rise into the Premier League's top 10 has come without keeping a clean sheet in their first 20 matches – compared with the leaders' 40pc shut out ratio. Lambert's men have, however, been prolific at the opposite end of the pitch with only the top five outscoring the Scot's side. Norwich's prowess aerially is underlined by the fact just 14pc of their 30 league goals have been scored outside the penalty box. Top scorers Manchester City and bitter rivals United in contrast have plundered just under a quarter of their goals from outside the opposition penalty area. Roberto Mancini's table toppers also have the best defensive record, having conceded only 16 goals, compared to Norwich's 35.
