Sunderland boss Dick Advocaat is still assessing where DeAndre Yedlin will fit in his team.
The on-loan Tottenham fullback only arrived on Wearside on Friday due to his involvement with the USA national team during the international break.
“I don't know enough about him yet, to be honest," said Advocaat.
“I've seen the videos of him and we saw him against Holland, when he did really well when he came on.
“But you can only see in training what he can bring and if he is better than the others.
“He only got here on Friday, so we need to work with him more."
