Psychologists.nutritionists,analysts & physiotherapists 4 cricket team

I was recently reading an article about former pakistani cricket greats being againsts the use of these kinds of specialist ( ie psychologists, nutritionists, comp. analysts etc)..Iam a ie hard foot fan as well as a die hard pakistan cricket fan.. the team that i follow is Arsenal..In 1997 Arsenal bought a french coach named Arsene wenger..Wenger has revolutionised arsenal foot ball club with his new methods..he has changed around the diets,training techniques,specific muscle modifications & mental strengh of the players..this has not only taken Arsenal to new height of winning 6 trophies in 7yrs, but has also lenghtened the playing careers of players..He did away with the fish & chips cultures replacing it with pasta which gives an individual longer energy levels..i could go on writing..While india are baking in theglory in pakistan, pakistan are wondering who to sack & who to punish without dealing with issues like the above…I suggest that we need a pure professional at the top who can look at these issues..Why not hire arsene wenger for the summer for advice..it would be invaluable
