Andy Murray set to take on Ivo Karlovic

Andy Murray is set to take on Ivo Karlovic today in the hope of reaching the quarter finals.

Murray revealed he will not underestimate the big-serving Ivo Karlovic as he kicks off his second week at Wimbledon on Manic Monday.

There will be a packed schedule as the fourth round action begins, with spectators on Centre Court being treated to the fifth All-England Club clash between sisters Serena and Venus Williams.

That match will be followed on Centre Court by Murray taking on the 6ft 11in Karlovic, who boasts the second-most aces in tennis history.

At 36, the Croat is the oldest male to reach the second week at Wimbledon since 1976, and he has utilised his greatest weapon to outstanding effect, smashing down 136 aces in the tournament so far.

┬áDay seven of the Championships will also see top seed Djokovic in action against Kevin Anderson, while Roger Federer will also face Roberto Bautista-Agut on Centre Court, all part of so-called ‘Manic Monday’ after a break in play on Sunday.
