Norwich City will look to defender Russell Martin as potentially crucial to preventing an at times dangerous Sunderland attack from gaining any kind of momentum tomorrow.

According to the EA Sports Player Performance Index, Martin has one of the best tackle success rates in the Norwich squad, completing 68.2 per cent of his 44 attempted challenges, committing only 10 fouls.

Robert Snodgrass has been vital as a creative force for Norwich this season, consistently moving forward with purpose into dangerous attacking positions. He has also completed a pass in his opponents' half once every four minutes he's been on the field.

Steven Fletcher continues to be Sunderland's primary threat of goals, despite increasing help from midfield from Stephane Sessegnon and Adam Johnson. According to the Player Performance Index, Fletcher has an excellent shot accuracy rate of 75.5 per cent from 49 attempts on goal, converting that sharp shooting into 11 goals.

Some of Carlos Cuellar's defensive work has been outstanding this season. The imposing Spaniard has an excellent tackle success rate of 86.8 per cent from 53 attempted challenges.

Sessegnon has been more than happy to test out opposing defences this season and Norwich's back four will have to be aware of the threat he poses. He currently sits third in the Player Performance Index for dribbles with 39.
