Slaven Bilic says his squad in his need of 'quality' in the midfield as a deal for William Carvalho continues to drag on.
The Portugal international has had a £40m price-tag put on him by Sporting Lisbon.
When asked if the club were any closer to signing the Euro 2016 winner, Bilic said: "Nothing new. I am not frustrated. It is a position we have been trying to do that (strengthen) for a couple of seasons now.
"We need someone to boost our team, quality and everything.
"We need that position and that is why we have offloaded some players to get the budget for him. I am not talking about the player (Carvalho), I am talking about the player for that position.
"The quality player not the quantity one. It is not easy to get them but we are doing our best."
