Winger Sammy is currently on-loan at Middlesbrough.
He told the Evening Chronicle: "I'm really happy for him. I hope he can continue to score goals. He's got a knack of scoring in Europe!
"I was sat at home watching the Kharkiv games with a few of my friends.
"You wouldn't believe how nervous I was despite him having never missed a penalty.
"But he slotted it away, which was great."
