Viktor Troicki returns this week from a one-year suspension for refusing to take a blood test, and is looking to receive a wildcard into Gstaad next week.

The Serb was selected for a blood test at Monte Carlo a year ago, but said that he had not been well and claims an anti-doping official told him he could ask to skip the test. Troicki gave the test the following day. He received a one-year ban, reduced on appeal from 18 months, and has protested his suspension.

"I really want to show everyone how unfair this decision was," he told television in Serbia. "But I also want to make up for my absence, though I don't know how long it will take before I am seen the same way as before.

"In some tournaments, there will be wildcards. Now we are waiting on confirmation from Gstaad. Then there will be some challengers in Italy.”

Troicki, 28, added that compatriot Novak Djokovic, who has consistently backed Troicki, would request some wildcards for him at Asian events. "Novak has been a big help to me," he said. "I trained with him at Monte Carlo, Dubai and Miami."

Troicki said his goal was to return to the Top 100 this season.
