However, having only made 14 appearances, Miku has now confessed that he regrets his decision.
"It was a mistake to go there simply because I cannot do anything," he said in an interview published in his homeland.
"At first I did not understand. I said to myself: 'How might come to play in the best league in the world and play no part in Scotland?' But then I realised that things had nothing to do with sport."
Miku has found the net twice during his 14 outings.
