the imports who played in IPL went home refreshed, our players were partying too hard, and also got too much money for them to work hard in the world cup - where it really matters. they concentrated too hard on IPL, after all thats worth much more than a national team performance where one century can work wonders for several more matches
The players are tired and do not have stamina to play football gracefully. Similar things happen in IPL world cup. Too much play and no rest is detrimental to health.
