Μετάφραση - Αγγλικά-Φινλανδικά - Do you believe in me?

or "Do you trust me", or it could be "do you believe me" as well

Translation meaning Do you think that I can do it? or Do you think I have the required skills and/or strength? (The same case used: Do you believe in Santa Claus = Uskotko joulupukkiin).
Using the verb trust the translation would be Do you trust me="Luotatko minuun?" meaning almost the same.

The other possibility "Do you believe me" (Do you think I am telling the truth). This meaning which I think is most common would be "Uskotko minua?" (NB different case used).
