Rio Ferdinand believes Arsenal’s Laurent Koscielny is the best defender in the Premier League (Video)

Man United legend Rio Ferdinand has claimed that when on form, Arsenal’s Laurent Koscielny is the best defender in the Premier League.

The former England and United captain turned BT Sport pundit, made those remarks after Arsenal’s impressive 3-0 victory over Greek side Olympiakos in the Champions League on Wednesday night.

Whilst striker Olivier Giroud will grab the headlines for scoring a hat-trick, Arsenal were also extremely thankful to their French defender Koscielny for being superb at the back, and the defender made some crucial blocks and interceptions during the match, to ensure Arsenal completed the miraculous escape of qualifying from their group.
