EXCLUSIVE BY KIERAN GILL AND MIKE DICKSON: The decision to award Brydan Klein a wildcard for Wimbledon has led to some disapproval after the British No 5's bad- tempered behaviour in Nottingham last week. Australia-born Klein, who switched allegiance to Great Britain in 2013, was punished by umpire Mohamed Lahyani for ball abuse, unsportsmanlike conduct towards a lineswoman and for shouting: 'You stupid, stupid person.' It cost him the match against Sam Groth at the Aegon Open in Nottingham and Klein, 27, was subsequently fined £3,500 by the ATP.
