Lee Johnson has described the signing of Patrick Roberts as an 'amazing coup' after the winger joined Sunderland from Manchester City - but warned that he will need time to settle in on Wearside.
Roberts has joined the Black Cats on an initial six-month deal, with an option to extend his stay in the summer, after his loan spell in France with City's sister club Troyes was cut short.
The Manchester Evening News is reporting that the up-front fee is thought to be nominal, but the deal could ultimately be worth up to £3m in clauses and add-ons depending on how he fares at Sunderland.
