It's a difficult time for the UK, with recent off-the-field events causing the Government to announce a 'lockdown' period.

Sunderland will be hoping that they can put together a positive run of form when they do return to action. The Black Cats are currently sat seventh in the League One standings, but are just three points adrift of the automatic promotion places.

One player that has played his part in their relatively strong run of form this season is Luke O'Nien, who has established himself as a firm fans favourite at the Stadium of Light.
