British tennis is set for yet more uncertainty at the top as it prepares to lose its Performance Director to Manchester City.
Simon Timson is to leave the Lawn Tennis Association to take up a comparable role at the Premier League giant after being the latest figure to try and solve the problems of elite player production in Wimbledon's host nation.
He has been at Roehampton for three and a half years, and will not be around to see if the measures he has introduced will yield any sustained success.
For Timson the switch to the Etihad is another switch in sport, having worked in both summer and winter Olympic disciplines as well as cricket before arriving in tennis.
