Former West Indies fast bowler Tony Gray believes the Australia series could be make or break for veteran batsman Chris Gayle, insisting he would give him just another two games to turn things around, if he were on the panel of selectors.

The 41-year-old Gayle has struggled to make a positive impact with the bat since being recalled to the team in February of this year, after two years away from the squad.

The batsman's selection to the preliminary World Cup squad has proven to be a source of controversy with opinion sharply split into two camps.  On one hand, many believe the batsman's ability to change a game within a few deliveries continues to make him an indispensable asset heading into the tournament, others point to his decline in explosiveness and fitness as evidence that the spot should be taken up a younger player.

His performances so far have done little to make a strong case for his inclusion.  In eight matches, against Sri Lanka, South Africa, and Australia, Gayle has averaged 12.71, with a combined 89 runs, and has a highest score of 31.  In addition, the batsman has a strike rate of 94.68, well below his career average of 139.71.

Speaking just before the start of the Australia series, Gray suggested the batsman could be running out of time to repay the faith of the selectors.

“I think initially the selectors did a good job of picking this T20 squad.  You have to give Chris Gayle the chance to show he has some kind of form, but if he is getting the opportunity and not firing, I would not pick him,” Gray told the Mason and Guest radio show.

Gayle is the all-time leading runs scorer for the West Indies in T20 international cricket, having scored 1716 in 66 matches.

"I think they need to have a serious word with Chris Gayle in the sense that he is 41 years old now, and obviously they have to have some sort of system where they say to Chris Gayle that 'we're giving you about nine games,'" Gray said.

"If you're not firing for nine games, then the remaining games before the World Cup, we have to give a young player', so that's the sort of system they need with Chris Gayle,” he added.

"If he doesn't fire against Australia for the first two games, I'm not taking him to the World Cup. That would be seven games - against Sri Lanka and South Africa - and the next two games would be nine games, he had an opportunity to fire.”

Gayle made just 4 runs in the opening match against Australia on Friday.
