Southampton chief Les Reed says a bid is in for a new signing.
Saints are seeking a replacement for Tottenham signing Toby Alderweireld.
Reed told the Daily Echo: “We have contacted clubs and made enquiries and bids as we speak, and we will be following that up in the next 48 hours to try and get something over the line as quickly as possible.
“What's important for Ronald is we get these players in so they are in pre-season training long enough to be prepared properly, which again is different to last year when it was all coming a bit late.
“We've got options and we've got initial bids in to see what we can do and we will continue to do that until we get someone over the line."
