FAST-bowling legend Glenn McGrath has lamented the fact that the abundance of Twenty20 leagues across the world has an adverse effect on bowlers and youngsters around the world.The Australian legend feels young fast-bowlers stop working hard after initial success.The 46-year-old, who claimed 563 wickets in 124 Tests and 381 wickets in 250 One Day Internationals (ODIs) during a 14-year career, is currently working with the MRF Pace foundation in India. McGrath wants young cricketers to continue working on their skills even after they achieve success.“Biggest issue which I find, probably not just in India, probably around the world is how hard they are prepared to work.“And if they do get a little bit of success playing in IPL or Big Bash in Australia, is that they get to that level and they think they have made it and they stop working hard and they stop training much,” McGrath said to the Times of India.“Young bowlers have to be prepared to work hard and then work even harder to stay there, there are no easy options or shortcuts.“Sometimes, I see young cricketers reach a certain standard then all of a sudden they get paid good money and they stop working.“I think money should always be secondary. It’s great that cricketers are earning good money. But if money is secondary, it’s all about going out there performing at their best and keeping themselves in the best condition.“Then that money will be there all the time. And I think that’s the attitude young cricketers should have. Ultimate goal should be representing your country,” the legend added.The fast-bowler is one of the most decorated players to represent Australia, winning three World Cup titles during his career, while his haul of 563 Test wickets is the most by a pacer with the top three positions occupied by spinners.
