The Armenia international is on-loan at Roma this season.
And he says: “When Mino Raiola called me to propose the Roma solution I didn't think twice, and I have no regrets.
"From day one I felt the appreciation of the fans and the club. I really like the people of Rome!
"(Coach Paulo) Fonseca? I didn't have him as a coach when I was at Shakhtar, although I saw his team play in the Champions League and he had impressed me a lot. His Shakhtar played fluently against big clubs like Manchester City and Roma.
"Coming here I got to understand his football better and I am sure that great results will come with him."
