Celtic striker Miku has put Premier League clubs on notice.

The Daily Express says the 27-year-old Venezuela international turned down Reading and Swansea to move to Celtic but has struggled to make an impact since arriving on loan from Getafe in August.

Miku told a Venezuelan newspaper: "It was a mistake to go there simply because I cannot do anything.

"At first I did not understand. I said to myself: 'How might come to play in the best league in the world (Spain) and play no part in Scotland?'

"But then I realised that things had nothing to do with sport."
