The South African midfielder has spent eight years at Everton in total.
The 34-year-old's existing deal at Goodison Park expires this summer and the veteran midfielder admits that he is growing frustrated over his efforts to clarify his future on Merseyside, which reflects what HITC Sport reported last week.
Pienaar is currently fully fit following an injury-ravaged 2015 which amounted to just one appearance, but he has figured off the bench in Premier League action in recent months, as well as starting two FA Cup ties - home to Dagenham & Redbridge and away to Carlisle United.
And the South Africa international suggested that he should not have to wait until the end of the season to discover whether he will be offered an extension.
“I’m 100 percent fit and felt in good form when I played some games in January,” Pienaar told KickOff.com. “I haven’t been in the squad for the last six weeks, I don’t know why, and obviously this is a concern for me. But that is the coach’s decision and I must respect that.
“Waiting until the end of the season to hear whether or not Everton wish to extend my contract is unreasonable, I feel. It’s not the way I envisaged ending my career at a club that has been such a major part of my life.
“My representatives have tried a number of times, unsuccessfully, to get hold of the club to talk about my future and get some indication, so I remain in the dark. Obviously I need to keep my options open because I would still like to keep playing for another couple of seasons at least.”
By virtue of the fact that he has spent a total of eight years as an Everton player, Pienaar, who initially joined the club in 2007, arguably deserves to know where he stands in Roberto Martinez's long-term plans.
He re-signed for the club on loan from Tottenham Hotspur in January 2012 after a trying six months at White Hart Lane, before joining on a permanent basis under David Moyes - who signed him twice - the following summer.
