Wimbledon 2012: Tsonga relishing 'huge' Andy Murray match

Jo-Wilfried Tsonga promises to "take his chance" in what will be a "huge" semi-final match against Britain's Andy Murray at Wimbledon on Friday.

The fifth seed, who beat Philipp Kohlschreiber to progress to the last four, admits he is not playing his best tennis but insists he is "mentally strong and ready" for the match.
