Jones, 26, said: "Of course we want players in. I think it's impossible for the same team to play every game of the season.
"Especially when you have a tough campaign like us. We have a thin squad at the moment and this season we are going to have loads of games. We've got matches in Europe, cup games and of course the Premier League to consider.
"We're going to need some rotation and hopefully the people at the club do eventually add some quality.
"We want to keep things fresh and the squad ticking over, so we need bodies in."
