Robert Kubica has admitted to having 'talked' with BMW-Sauber in the wake of his recent public criticism of the team, but added that 'nothing has really changed' as both his 2008 title hopes and his future with the Munich and Hinwil-based outfit hang in the balance.

Having at one stage led the Formula 1 World Championship standings this season following his stunning breakthrough Canadian Grand Prix triumph, Kubica enters the final four meetings on the calendar - beginning with the sport's inaugural night race in Singapore this weekend - trailing Lewis Hamilton by 15 points, with just 40 remaining to play for.

The finger of blame for that situation has been pointed at BMW's failure to match the development pace of McLaren-Mercedes and Ferrari as the campaign has progressed, with the Polish star suggesting that his cause may have been aided had the squad spent more time focussing on his challenge for the crown rather than on repeated efforts to bring under-fire team-mate Nick Heidfeld back up-to-speed in qualifying.

Indeed, despite Kubica's 'clear-the-air' talks with the team's management, BMW has seemingly slipped even further away from the front-running pace in recent weeks, with both F1.08s finishing behind a Scuderia Toro Rosso and a Renault in the Italian Grand Prix at Monza last time out. The man from Krak?w confesses that the situation has left all concerned rather perplexed.

"We talked, but nothing has really changed," the 23-year-old is quoted as having said by F1SA in Singapore. "Lately the gap has gotten bigger. At the beginning of the season we could fight with them sometimes, but then the top teams became stronger, Renault got closer to us, [and] the same with Toro Rosso.

"I don't know why. We made some mistakes with some parts but recovered very fast from that. The reaction of the team was very good, but we somehow did not succeed in finding what really makes the car faster."
