Andy Murray's reunion with coach Ivan Lendl will help perfect the mental game required for another Wimbledon title challenge, says his mother Judy Murray.
Britain's world number two, 29, won Wimbledon, the US Open and Olympic gold with Lendl from 2012 to 2014.
"One of the big things Ivan helped Andy with when they worked together the last time was the ability to set his focus when he got distracted," said the former Great Britain Fed Cup captain.
"It's good to have him back."
She added: "When you get into the critical moments there are so many good players that you can't afford to have momentary lapses in concentration.
