Southampton have reportedly made a swift move to replace Liverpool-bound Adam Lallana.
After a large amount of speculation, it was confirmed earlier today that England international Lallana had sealed his switch from the St Mary's Stadium to Merseyside.
However, Saints boss Ronald Koeman has not rested on his laurels and has submitted an undisclosed offer for FC Twente winger Dusan Tadic, which has been accepted by the Dutch club, according to Sky Sports News.
Tadic, 25, joined Twente from FC Groningen two years ago for a fee in the region of £6m.
