Alessandro Matri says he hopes to have done enough to earn a permanent move to Italian giants Juventus.
The Old Lady signed the striker on a six-month loan from Cagliari in January with the option to keep him for €15.5m.
The Italian international responded with nine goals, to add to the 11 he got in Sardinia, including a strike in last night's 2-2 draw with Napoli.
"I'm pleased with what I've been able to do and therefore I hope to stay here, but considering the result of the season I can't be fully happy," he stated.
Juve have had a campaign to forget, finishing seventh in the League and failing to qualify for Europe.
"We're all upset about how the season's gone. This year we've only experienced bitterness, next year we only want to have satisfaction," he added.
Boss Gigi Del Neri is set to pay for the failure with his job as Siena tactician Antonio Conte is already lined up to replace him.
"I still don't know anything about who will manage us," Matri added. "I know that Del Neri won't be here anymore.
"I owe him a lot because he trusted me since I arrived and for this I would like to thank him very much."
