Southampton boss Nigel Adkins is hopeful the Saints will make more additions to the squad before the end of the month.
"The way the summer period has gone, we've been linked with several players," he said when asked about the Uruguay international ahead of Southampton's clash with Wigan.
"I think it is fair to say if and when somebody signs then we'll announce it. Until then, everything is all speculation.
"He said, she said, they said - all that sort of stuff. I think if we can just concentrate on what we're doing with players, obviously this week is going to be a busy week for everybody."
Asked whether there was any update on Phillips or reported interest in Blackburn Rovers Martin Olsson, Adkins added: "We'll concentrate on the Wigan game. It is going to be an intense week next week, I would have thought.
"I'd like to think we are going to be very active in the window because I know how hard people working behind the scenes here at Southampton.
"We want to improve and it is fair to say that now the transfer window is coming a bit of closer [to ending], more decisions are made.
"I have gone public saying we need to bring in another centre-half, if not two, so we'll see what the week brings."
