Karun Chandhok is still refusing to rule out getting a one-off race seat at Team Lotus later this year when his native India hosts its inaugural Grand Prix.
The 27-year-old made an abortive debut with HRT last year and in 2011 is the reserve driver at Lotus, where in Melbourne and Turkey he has enjoyed Friday practice duties.
But it has been rumoured for some time that race regulars Jarno Trulli or Heikki Kovalainen could move over for him late in October, when New Delhi makes its Formula One bow.
Chandhok admitted to PTI that he will be disappointed if that is not the case.
"Well yes, there will be disappointment," he said.
"You need to be slightly patient in such kind of situations and my view is to believe in the medium to long term.
"Yes, I will back in the F1 as a race driver but this year or next year, we will wait and see," added Chandhok.
