Manchester legend Ricky Hatton is having a tough time picking his countryman, Amir Khan (31-4, 19 KOs), to beat eight division world champion Manny Pacquiao.

The fight between Khan and Pacquiao is now being targeted for May 20 in UAE (May 19 in the United States), according to the Filipino superstar's adviser, Michael Koncz.

Hatton has his own experience with Pacquiao. They faced off in 2009 at junior welterweight, with Pacquiao scoring a brutal one-punch knockout in the second round.

Khan has been out of the ring since May of 2016, when he moved up to 155-pounds to challenge Saul "Canelo" Alvarez for the WBC middleweight title. While Khan did very well in the early rounds, he was knocked out cold in the sixth round. He later had surgery on his right hand, which kept him on the shelf for the remainder of the year.

The fight with Canelo marked the third time that Khan suffered a vicious knockout loss. Khan was knocked out against Danny Garcia and also early in his career against Breidis Prescott. Khan has also been down nine times throughout his career, which has obviously caused many in the sport to question his ability to take a good punch.

Hatton is worried that Khan is biting off a little too much by facing Pacquiao on the back of such a vicious knockout loss. Pacquiao is now 38-years-old, but Hatton still views him as one of the best in the sport.

"Manny has seen better days but I think he might still have a bit too much for him [Khan]," Hatton told Business Insider. "I hope I am wrong but Amir is coming off a heavy knockout defeat and that's his third heavy knock out. There are only so many times you can come back from [the] brutal knockouts Amir has had."
