Former boxing world champion Barry McGuigan has advised Amir Khan not to take a fight with Filipino legend Manny Pacquiao.

Writing in The Mirror, McGuigan said: "I would caution Khan against another high-octane super-fight off the back of a crushing defeat last time out. Khan can't help himself - he loves the show.

"But we saw when he stepped up from welterweight to middleweight to fight Saul Alvarez the dangers of biting off more than he can chew.

"Even at this advanced stage of Pacman's career anything less than 100 per cent would not be good enough for Khan, and even that might not be sufficient," he added.

Pacquiao recently put up a poll for his fans on Twitter asking them to choose between Khan, Terence Crawford, Jeff Horn and Kell Brook as his next opponent.

Who do you want me to fight next in the UAE?

Khan won the vote but there has yet been any movement on confirming his next bout. Pacquiao is coming off a unanimous decision win over Jessie Vargas where he won the WBO welterweight title.

Khan is coming off a devastating knock-out loss against against Saul Alvarez last May.
