Wimbledon 2012: David Mercer predicts Murray-Djokovic final

BBC Sport commentator David Mercer believes Andy Murray will defeat Jo-Wilfried Tsonga in Friday's penultimate round and become the first British man to compete in a Wimbledon final for 74 years.

He also says that although "his heart says Roger Federer" his head thinks Novak Djokovic will prevail in their semi-final clash, the first of Friday's matches on Centre Court.
