Zeljko Krajan criticises the attitude of British No 1 Laura Robson
British No 1 Laura Robson has been criticised for lacking maturity and commitment by her former coach Zeljko Krajan.

The 19-year-old linked up with the Croatian following the Olympics and the partnership appeared to be flourishing as Robson defeated Kim Clijsters and Li Na to reach the fourth round of the US Open.
But Krajan, who guided Dinara Safina to world No 1, parted ways with Robson last week - with a clash of styles between the hard taskmaster and the laid-back Brit.
Krajan told The Times: "The mentality is different. I did expect more from Laura but when it doesn't go that way any more it is not the time to stay.
"She was not mature enough to do this kind of work enough times for me. She needed to be more serious and to commit herself more.
"She had to do this every day, not only in the big tournaments."
The 19-year-old has continued to climb the rankings this season and, at number 41, is within sight of being seeded at the French Open later this month.
But there have been poor results, too, with six first-round defeats and the disappointment of Great Britain's failure to reach the Fed Cup World Group.
Robson sealed her first win over a top-five player on Monday, beating Agnieszka Radwanska in the second round of the Madrid Open, but was then beaten by former world number one Ana Ivanovic.
