Southampton manager Russell Martin admits Romeo Lavia can be sold this month.
Lavia sat out last night's Carabao Cup defeat at Gillingham. The midfielder has been the subject of multiple offers from Liverpool.
"We have a big group, but only so many players that can help us," Martin told BBC Radio Solent afterwards.
"There needs to be movement for sure. [Director of football] Jason [Wilcox] has been very honest about it, and he feels exactly the same way, and so do the ownership group.
"But also, there needs to be movement that suits us as a club. I don't envisage anything changing between now and the weekend, but it's football, right, so anything can happen.
We'll be prepared for everything and anything. The guys we left behind today isn't out of lack of respect for the competition or anything like that."
He added: "It's about we need to see everyone out on the pitch at some point because we might need people.
"Some people we think might go might end up staying, and some people we think are gonna stay might end up going. It's so fluid."
