'Mother knows best' for both Murray and Istomin ahead of fourth round US Open clash

Defending US Open champion Andy Murray has an exciting opponent in the form of Uzbekistan's Denis Istomin in the fourth round on Tuesday, as both the players have been helped by their mothers to brush up their tennis skills.

According to The Guardian, while Andy Murray does not discount the possibility of his mother, Judy, coaching him when he gets towards the end of his career, Denis Istomin, already relies on the expertise of his mother, a rarity on the men's Tour.

Murray said that there are not a lot of players, who get coached on by their parents.

Istomin, who lives in Moscow but still plays Davis Cup for his native Uzbekistan, is in excellent form and pays tribute to his mother for organising and overseeing his tennis, although he admits the arrangement presents logistical difficulties, the report said.

Murray said that tactically, her mother was a very good coach and even liked to watch videos of other players, adding that she helped him and his brother until 11, 12 years old.
