In the Riveira post fight interview, Hatton said that after Tszyu he would be interested in fighting Cotto. if Hatton puts on a good performance (win or lose) and ODLH keeps his old ass retired, we might see Cotto vs Hatton in 2008.
Cotto will end up fighting the winner of Mayweather/Hatton sometime next year. Hopefully DLH stays outta the picture because he might put this matchup on hold.
