He said: "It was just a fantastic feeling at Spurs and I'm very happy.
"First, we played like a team - and to win 5-1 against Tottenham is unbelievable. Then to score four goals was just amazing.
"I got the ball signed and I will send it home to Bosnia with my other things. This will be my first matchball.
"I scored a hat-trick before but I did not take the ball. I do not know why!"
