One of the last significant pieces of the 2014 'silly season' puzzle will fall into place on Tuesday, the German news agency SID reports.
The reports said Nico Hulkenberg's switch from Sauber to Force India, where he tested and raced in 2011 and 2012, will be announced officially by the Silverstone based team later on Tuesday afternoon.
But Adrian Sutil, the Force India incumbent, might not yet be out of the frame, although he has been strongly linked with a move to Sauber to replace Hulkenberg at the Swiss team.
German Sutil's manager Manfred Zimmermann on Tuesday said the future remains unclear.
"Still nothing has been decided -- we are in the middle of the negotiations, hoping for a quick solution," he claimed.
"The formula one driver market is so complex that you can never be sure of anything," added Zimmermann.
