Unai Emery tried, unsuccessfully, to condition his Arsenal side'sbeer777 first game of the season against Manchester City in his favour.On the opening day of the Premier League campaign, his new club were defeated on home turf by Pep Guardiola's reigning champions.City's head groundsman Lee Jackson has now revealed in a statement to the Daily Mirror that Emery warned his own ground staff not to water the pitch that day, despite August 12 being particularly hot in London.It was quickly picked upon by Jackson upon inspecting the grass and he told Guardiola about the conditions for the game which City ultimately won 2-0."After 20 years with the same coach, they didn't water the pitch before a game or at half-time and that is very unusual," Jackson said."It didn't do them any good in the end."Jackson also praised City's coach for the obsession he has with all aspects of the game,beer777 while also acknowledging that Arsenal's turf isn't the worst he has came across in the Premier League."Pep's attention to detail is phenomenal, it is something I've never experienced before," he added."Most coaches now want the grass to be wet and short because the ball travels faster but I remember when Tony Pulis was at Stoke City."You couldn't even see your feet on the grass when you walked, that's how long it was!"
