Having confirmed a deal with Jos? Mar?a L?pez last week, the USF1 team now appears to be close to announcing its second driver, with Adrian Valles said to be in 'well advanced' talks with the Carolina-based operation.

According to reports by Spanish newspaper, Marca, the 23-year-old will sign a one-year deal 'imminently'.

"I'm sorry, I can't talk," Valles told sportinglife.com when asked about the rumours. "I just hope things don't go wrong."

Valles, who was a test and reserve driver for the Spyker F1 team in 2007, won the Superleague Formula title in 2009.

If he is confirmed by the Peter Windsor and Ken Anderson-led outfit he will become the fourth Spaniard on the grid for F1 2010, along with Ferrari's Fernando Alonso, Sauber's Pedro de la Rosa and Scuderia Toro Rosso's Jaime Alguersuari.
