The two-time World Champion currently finds himself in fourth place on the standings after two fourth places and a fifth, but knows a much improved race at Jerez is needed this weekend if he is going to move up the table in the near future.
"For me the bike is more competitive than last year, as Vale has demonstrated. I just need to find my way to go fast again," the Spaniard told crash.net.
"I think in Qatar I was able to fight for the win apart from this thing with the helmet. Then I was a little bit weak [with sickness] in Austin and I had some problems in Argentina with the tyres.
"When you are on the top and faster than your rivals if you have some little problems it doesn't change your position. But when you are a little bit slower and have some little problems, now there are a lot of riders very competitive in MotoGP and you are in third fourth or fifth position.
"So we have to improve this two or three tenths and then we will again be always fighting for the win."
Considering he is already 29 points behind his Yamaha team-mate, a podium finish is the bare minimum for Lorenzo on Sunday.
"Valentino won two races so for sure he has much more points compared to us, but obviously it could be worse, like last year. But obviously it's not the places where we want to be. At least we want to fight for the podium and I think Jerez is the perfect place to do it. So we are going to try."
