Can't speak Russian but hope you understand this:

M1/LMB (Left mouse button) to dribble and ball control.
To keep the ball for yourself to look all the way down.
For moving the ball forward while dribbling you have to look a bit more up.

For shooting you have to charge with M2/RMB (Right mouse button)
The difference here is that it has a charge mechanic. You have to make sure you charge up the power you wish and release it when you are close enough to the ball.

It can all be tricky to learn in the begin but once you understand it bit for bit it's very easy.
