champion greg norman, who still holds the joint course record at augusta national, spoke to bbc world news at his florida home recently. he's a big fan of the 32—year—old johnson and thinks he has what it takes to dominate the sport. iam i am really impressed with him. combination of power, finesse, calmness beyond calm — nothing seems to faze him. but above all, consistency. i mean, he is, he has been consistent for over a decade 110w. been consistent for over a decade now. he has won a golf tournament every year for over a decade. now. he has won a golf tournament every yearfor over a decade. so, he is not like he hasjust appeared in the last — since he won the us open. he has been around for a long period of time. and i think he has finally realised the responsibility of what golf means to him. because his priority on the golf course probably didn't match the priority off the golf course. and you have to get to a certain point in life where you realise that, oh, my gosh, yes, my profession is golf and i have to do certain things a certain way and i have to conduct myself a certain way. so, at the end of the day, i think, he has merged all those responsibilities internally to realise that he now is at a place where he can just go ahead and just do what he loves to do, and that is just play golf. and if he can just do that he is going to go ahead and he will dominate for a long period of time. to cricket where fast bowler mohammad irfan has been banned for a year by the pakistan cricket board for twice failing to report approaches by bookmakers linked to spot—fixing.

something special. hopefully, you know, the administration people, the important people upstairs are going to look at that and see a way of making sure test cricket doesn't fall away, as t20 sort of grows and grows because, for me, test cricket is the pinnacle, you know, the toughest test, both mentally and of your cricketing skills, so, for me, i think it is a huge place for it still. in the
