'There are still too many outstanding issues' - Toro Rosso
May 24 (GMM) The engine deal between Toro Rosso and Renault is reportedly not yet ready to be announced.
"There are still too many outstanding issues," a Toro Rosso source is quoted as saying.
Alain Prost, on Renault's executive committee, said on Thursday that he expected progress to be made this weekend as the French marque signs up its 2014 customers.
"I'm not negotiating with the teams myself but we all know that it's going to be accelerating during this weekend," he said in Monaco.
"I cannot say all the (announcement) dates for all the teams but I hope very quickly."
