"We're very clear about our goals, Lovren was one of those and we signed him in the way we wanted and when we wanted to sign him," the Argentine said.
"A lot of players want to come to Southampton, we are a well respected club and we have a clear path as to where we want to go.
"But I want to make a point that we are Southampton and we decide when we want to sign players, we set the times when they go through.
"There have been a lot of rumours with players coming to us which shows we are professional and ambitious."
Southampton have also been linked with other high-profile names recently, including Brazilian striker Leandro Damiao, Roma forward Pablo Osvaldo and Valencia midfielder Ever Banega, and Pochettino indicated reports were not without substance.
