Amir Khan endured a testing night in Birmingham on Saturday but did enough to see off Samuel Vargas.The 31-year-old, competing in his second bout since making his comeback earlier this year, recorded a unanimous points victory over his Colombian-born opponent.However, Khan survived a second-round knockdown and failed to get the knockout that he craved, despite flooring Vargas with a straight right in the second round.Khan regained his composure after suffering his own knockdown moments later and went on to register a 119-108 119-109 118-110 win.Watching ringside was Kell Brook, who remains keen to face Khan, even if it means dropping down to the 147lbs welterweight division to secure it.Khan is also keen on the bout, although admitted in his post-fight interview that Manny Pacquiao is the fight he wants most."The only fight that works for me over Kell Brook is Manny Pacquiao," Khan said after the fight, per BBC Sport. "I want him. He is my number one pick. If not, we go back to the drawing board and if it's Kell Brook it's Kell Brook."

Froch gave his honest thoughts about Khan's display

This wasn’t a vintage performance from Khan, who recorded a first-round TKO over Phil Lo Greco back in April, but he was still the deserved winner on the night.

Carl Froch provided analysis for Sky Sports and raised eyebrows with his brutally honest comments about Khan’s display in the moments after the final bell.

“It’s a mediocre performance,” the 41-year-old said on Sky Sports. “What we giving it? Five, six? You need to be eight, nine, ten if you’re going to be stepping in with Keith Thurman or Danny Garcia - you know, that kind of level - you’ve got to be realistic about the level of opposition.”

He continued: “We’re forced to look at it at world level. Amir Khan has been up at world level and he wants to get back up there. Is that the kind of performance that’s going to convince you that Amir Khan can now be world champion at 147lbs?”

Reaction to Froch's comments on social media

While a few people agreed with Froch’s assessment, most boxing fans seemed to think his comments were unnecessarily harsh…

By the way, here's how Froch scored the fight...

Froch further backed up his comments in an interview with IFL TV, in which he added: “It’s a 12-round lacklustre performance against limited opposition in Vargas, who we’ve seen when he steps up to the likes of Errol Spence and Garcia, he gets absolutely wiped out and outclassed - and knocked out.

“Fundamental point is: at world level, that performance from Amir Khan will not be enough to beat them top boys in that division.”
