Former Wimbledon champion Goran Ivanisevic believes Andy Murray is already showing signs of improvement in 2015 after what the Croatian believes was a disappointing campaign last season.

Murray has made a positive start to his Australia Open
campaign and booked his place in the third round of the competition with a straight-sets win over Marinko Matosevic on Wednesday.

The Scot is now preparing to go toe-to-toe with Portuguese star Joao Sousa in the third round of the Grand Slam event on Friday.

Ivanisevic has admitted he questioned Murray’s decision last year to call time on his spell under coach Ivan Lendl, after he won two Grand Slam titles while working with the Czech-born American.

However, the 2001 Wimbledon champion has seen improvements from the British number one over recent months and believes the 27-year-old could well add to his Grand Slam tally in 2015.

He was quoted by the BBC, saying: “Andy is a great tennis player, a great competitor, he’s going to be back and he’s going to win more Grand Slams. If not this year, next year.

“He can easily win a Grand Slam this year. What he played last year was way off the standard of Andy Murray.

“There was some brilliance but overall it was medium.”

As Murray continues under his current coach Amelie Mauresmo, he must next get past Sousa before some far tougher challenges with the likes of Grigor Dimitrov, Roger Federer, Rafa Nadal and Novak Djokovic still in the competition down in Melbourne.
