Jurgen Klopp optimistic about scan on Philippe Coutinho's ankle injury

Liverpool manager Jurgen Klopp remains optimistic about Philippe Coutinho's ankle injury after the influential playmaker was carried off on a stretcher in the 2-0 win over Sunderland.

The Brazil international was caught by Didier Ndong's follow-through half an hour into the game and later left Anfield on crutches with his right foot in a protective boot but he will not be able to be scanned until Sunday at the earliest.
