Sunderland boss Roy Keane has raided his former clubs to bring in Stanislav Varga, Ross Wallace and Liam Miller.
He has also brought in Wigan striker David Connolly to cap a sensationally busy day in the transfer market for The Black Cats.
Having already brought in Dwight Yorke and Graham Kavanagh earlier on transfer deadline day, Keane decided to venture into the market again to snap up Celtic pair Varga and Wallace in a double deal potentially worth more than £1 million.
Scotland Under-21 international Wallace (pictured) has signed a three-year deal and will provide Keane with options both in midfield and defence.
He made more than 50 appearances for The Hoops and is tipped to become a regular in the senior Scotland team.
33-year-old Varga returns to Sunderland more than three years after he left The Stadium of Light for Glasgow.
The Slovakian defender's experience will be crucial as The Black Cats look to arrest their poor start to the season.
Keane also tempted former Manchester United and Republic of Ireland team-mate Miller to join him at Sunderland.
Miller has agreed a three-year deal with the Championship strugglers and joined on a free transfer.
In one final bit of business, Keane then captured Connolly, another Irishman, for an undisclosed fee.
