Marin Cilic has admitted that he needs more time on the court before he returns to his best form.
The world number nine crashed out of the Barcelona Open at the second-round stage earlier today following a 6-4 6-4 defeat against Victor Estrella Burgos.
It was just Cilic's third tournament of the season after recovering from a shoulder injury, and he concedes that he has much improving still to do.
"I was not too happy with the way I played," he told reporters. "I made a lot of unforced errors. I feel I still need several matches to get my form to a good stage."
Estrella will now face Martin Klizan in the next round.
