Marin Cilic goes for a hat-trick of titles at the PBZ Zagreb Indoors this week but he will face stiff competition from Ivan Ljubicic and Richard Gasquet.
After the Australian Open, the ATP Tour splits off into three. The big servers head back to Europe for the month long indoor swing, the clay-courters head off to South America and the rest hit the States for the lead-up to the first Masters Series events of the year.
Zagreb is the first stop on the European indoor swing. After the heat of Australia, acclimatising to chilly Croatia can be quite a shock to the system. But it is not just the temperature that changes. After the medium paced hard courts of Melbourne Park it's back to quick-fire tennis with the Zagreb courts among the fastest on the circuit.
Cilic has cleaned up over the past two seasons, relishing the home support and the fast, low bounce. He's made a decent start to the new year as well, reaching the fourth round in Australia.
He will face stiff competition from Richard Gasquet. Probably the best volleyer in the draw, Gasquet excels in these conditions so he should go far. 2006 champion Ivan Ljubicic should also be in for a shot.
As for outsiders, German serve-volleyer Philipp Petzschner should enjoy some success and look out for last year's runner-up Michael Berrer.
