One field where Arsenal was strong as rock last season is their defence. They have been tight lipped when it comes to conceding goals. Laurent Koscielny and Per Mertesacker defence partnership was really successful for Arsenal. Koscielny is a fast aggressive defender while Mertesacker likes to sit back. When this defence partnership started a match together in 2013-14, they were dribbled past only 0.7 times per game. This partnership averaged 4.5 interceptions per game.
Arsenal’s midfield was one of the strongest in Premier League last season. But towards the end, injuries of Aaron Ramsey and Mesut Ozil made all sorts of problems for Wenger. With the signing of Alexis Sanchez, one can easily see the inclusion of more goals in this midfield. The Chile International has shown his class in Brazil. But Arsenal still needs someone who can control the game with his physicality. Mathieu Flamini and Mikel Arteta nay be good midfielders, but defensively, their contributions were not as great.
