RAIKKONEN WARNING FOR MERCEDES
Kimi Raikkonen has warned Mercedes to up their game after a worrying start to testing for the new McLaren.
The McLaren's Mercedes engine has suffered reliability woes since it made its debut last week and Raikkonen confessed he is concerned by the problems.
The Finn missed out on the world championship last season, largely due to a string of engine problems, and he is concerned history could repeat itself this term.
He told http://www.autosport.com: "They are not where they should be and they need to improve. On the engine side we have a lot of work to do.
"We have been testing for a long time but we have not been able to make progress. It is definitely our weakest link now, but improvement is coming.
"It is the first time I am in the car. I know there is a lot of work to do but they are improving, and I know what is coming.
"I am slightly worried but not too much. Sure I can expect more but now we'll wait for a proper engine and we'll see."
