The Swedish international has struggled for first-team football this season and is about to return from a knee injury.
One deal was a hit, the other a miss.
Will Buckley struggled to make an impact at Leeds and was eventually sent back to the Stadium of Light after the man who brought him in Uwe Rosler left the club.
Liam Bridcutt on the other hand has been a star.
So if Leeds were to make a move for a Sunderland player again, who should it be?
Perhaps Sebastian Larsson should be on the radar.
The Sweden international, who has 80 caps for his country, is soon to return from a knee injury, as reported by the Sunderland Echo, but has struggled for regular first-team football this season. He has only started five Premier League games this term and his place in the Sunderland is certainly under threat.
He will also need to rehabilitate from his latest injury. Sunderland cannot carry passengers at the moment so a loan deal could also help in that regard.
The 30-year-old can play central midfield or right-wing and would be a fantastic acquisition for Leeds.
Plenty of names are being linked with Elland Road at the moment, but perhaps they should head back to Sunderland and ask for a third favour this term.
