Alexander Rossi says he is talking to the Manor Racing team every day about a full-time move into F1 this season, but says he doesn't know when a final decision will be made.

The 2015 GP2 runner-up became the first American to start an F1 race in eight years when he joined Manor for five outings during the latter portion of last season.

Proving an instant match for team-mate Will Stevens, Rossi was tipped to secure a full-time drive for 2016 as a result, but with just two weeks to go until pre-season testing gets underway in Barcelona, the British team is yet to reveal either of its signings.

Even so, Rossi confirmed he is still at least in the running for the drive, adding that he is 'positive' the decision will come out in his favour.

"Talks are every day," he told Sky Sports F1. "I think the deadline is really when cars roll in Barcelona in a couple of weeks,"

"Things sometimes get pushed out in this sport and it is something I am used to and hopefully it doesn't go on to much longer. Things are looking positive and hopefully we get it done very soon."

Though it has made a number of key signings in its technical department, as well as secure more competitive Mercedes power for 2016, Manor has given little away about which drivers it is talking to.

As well as Rossi, GP2 race winner Rio Haryanto is believed to be in talks, while DTM champion and Mercedes prot?g? Pascal Wehrlein is also considered to be in the hunt.
