Scott McDonald will depart Middlesbrough this summer and could land at Millwall according to reports.
The Australian striker joined the Teessiders three-and-a-half-years ago but is heading toward the Riverside Stadium exit door.
McDonald is entering the final year of his contract but Boro boss Tony Mowbray is keen to get the former Celtic star off his wage bill.
Millwall are showing considerable interest and will reportedly open talks with the 29-year old who will become a free agent.
