Moyes says he has several irons in the fire.
"I don't have many options and we don't have big cash but I will try to freshen things up," said Moyes.
"I'm just looking; we need some freshness for the second half of the season.
"A lot of my time in the next week will be devoted to trying to get someone in. But more of my time will be devoted to trying to win the games we have (against West Brom and Aston Villa) because you can only bother about the players you have.
"I will concentrate on the players we have at the club. If I am fortunate to get someone in then great, but we will try to move forward with the players we have."
