Mar.25 (GMM) Robert Kubica is "definitely" in the running to return to Formula One with Lotus in 2014.
Turning down an offer to return to circuit racing in the German touring car series DTM this year, the Pole has got off to a highly competitive start as he prepares to contest the second-tier world rally championship in 2013.
The 28-year-old admits he cannot currently drive a single-seater due to the limitations of his still-injured right arm, but he has not ruled out a return to F1 at some point.
It was believed the relationship with Lotus had subsequently broken down, but Frenchman Boullier now insists he would have Kubica back.
"If Robert is completely ready for a return to Formula One, he definitely would be among the candidates," he told Russia's f1news.ru, when asked about Lotus' 2014 lineup.
Currently, Lotus' number 1 driver is Kimi Raikkonen, but the Finn is yet to commit beyond the end of his 2013 contract.
Boullier was asked if Raikkonen will still be in F1 next year, and he admitted: "It's a very good question! I don't know the answer."
Another candidate to join the team in 2014 is therefore Davide Valsecchi, the reigning GP2 champion who has signed on this year as Lotus' official reserve.
Asked what chance the 26-year-old Italian has of racing in 2014, Boullier answered: "He has a better chance than anyone else.
"We have some plans for this season and we will see how he copes with his work -- on the track and off.
"Not in the course of a Grand Prix (weekend), but he will test with the old car."
