Birmingham City boss Gary Rowett says Demarai Gray is attracting interest from across Europe.
Gray has been watched Southampton assistant coach Erwin Koeman.
“I think we'll have a pretty good grip of whether it's going to happen this window - and at the moment I'm sure there's been a lot of interest," Rowett said.
“It was quite funny the other day because there was a story around that I think Southampton's head of recruitment was at the game.
“You can put him on a list of about another 40 heads of recruitment that have been at the games. “Every week every top club and some clubs from Europe watch.
“We have everyone there so at the end of the day anyone that is interested has seen enough of Dimmy to make a pretty informed judgement."
