Chelsea boss Rafa Benitez's scouting dossier of Wigan Athletic has made its way to the press.

The Daily Mail says it assesses the strengths and weaknesses of Roberto Martinez's team ahead of their Barclays Premier League clash.

Each opposition player was also assessed and some of the comments made grim reading for Martinez's squad as they struggle at the foot of the table.

Skipper Gary Caldwell is 'a ball watcher', 'rash in the tackle' and Chelsea's players were encouraged to 'run at him!' because he is 'slow to turn'.

Central defensive partner Paul Scharner is also highlighted, for being a 'ball watcher' and 'uncertain' after returning to Wigan on loan from Hamburg last month.

The analysis of Wigan's tactics was put together by Benitez's first-team opposition analyst Xavi Valero ahead of a team meeting on Friday.

Valero, 39, who worked with Benitez when he was manager of Liverpool, is one of the leading figures in the game in performance analysis.

The former Mallorca keeper has a masters in sports psychology and gained his goalkeeping badges from the Spanish Football Federation. Benitez went through Valero's document line by line with the players on Friday afternoon and used video analysis to help illustrate key tactical points.
