Millwall have lodged a bid for Swindon hot-shot Charlie Austin, skysports.com understands.
Highly-rated striker Austin is one of the most-sought after players in the country following his goalscoring exploits for Swindon last season.
The 21-year-old, signed from non-league Poole Town last October, notched 20 goals in just 32 starts last season, helping to fire the Robins to the play-off final.
Millwall have held a long-term interest in Austin after coming up against the striker last season in League One.
Kenny Jackett's side have now firmed up their interest in Austin with a bid for the forward as they look to test Swindon's resolve to keep hold of their star striker.
A number of other clubs are believed to be monitoring Austin's situation at the County Ground and they could move for the player following Millwall's offer for the striker.
Swindon are loath to lose Austin, who has scored two goals in five games this season, as they look to build a side capable of challenging for promotion, but they could face a fight to keep the striker in the wake of Millwall's bid.
