Liverpool take on the Gunners on Wednesday evening at Anfield, in the first of four games over an 11-day period.
With his squad severely depleted due to a host of injury problems in recent weeks, the German provided a positive update in terms of his centre-backs.
Speaking to reporters at Melwood on Monday afternoon, Klopp said that Sakho “wants to be available.”
“We’ll see,” he explained.
“The situation now is better than two or three days before, because Kolo will be available.
“So we have a senior centre-back!
“Mama wants to be available, hopefully we can use him and we will see.
“Martin of course is not to think about. Dejan feels good, but the time off [with] injury [is] only six days.
“There will be a moment where we will decide if there’s a risk, but that’s not for the moment.
“So we have probably Kolo and Mama, and the next one is Lucas [Leiva], so three senior centre-backs.”
Ilori may come into contention for a starting role against Arsenal, but it is more likely that one of Sakho and Lucas partners Toure at the back.
“Jordon Ibe, Jordan Henderson and Mama, [as] I spoke about—these are three good news [stories],” he continued.
“Milly is still in training.
“It’s all good news. That’s it.”
Arsenal are on course to challenge for the Premier League title this season, but with Klopp having rested a number of key players in Friday night’s 2-2 draw away to Exeter City in the FA Cup the Reds can be hopeful of a result.
