David Moyes has challenged Adnan Januzaj to step up and fire Sunderland to safety after the Belgian was jeered off the pitch by the club's own supporters.
Januzaj, the 21-year-old playmaker on loan from Manchester United, was substituted in the 66th minute of Sunderland's 2-0 defeat by West Brom on Saturday.
First-half strikes from Darren Fletcher and Chris Brunt consigned Sunderland to a sixth loss in eight Premier League games and Moyes' side dropped to the foot of the table.
'I am probably the toughest one on Adnan because I know what he has got,' Moyes said.
