Manchester United risk missing out on Livingston striker Matthew Knox today.

The Daily Record says the Scottish sensation spent two days on trial at United last week before returning north after injuring a toe.

Old Trafford staff now want the Livingston man back at the club to run the rule over him AGAIN.

But Norwich are ready to nip in and launch a bid of their own to bring him to Carrow Road.

And the chance of a permanent switch to England could see United miss out.
