Roma midfielder Radja Nainggolan feels Liverpool are the "toughest" team left in the Champions League.
While Real Madrid take on Bayern Munich, Roma are up against Mohamed Salah's Liverpool.
Nainggolan said, “I wasn't happy with the draw, because in my view Liverpool were the toughest team out of the three. It's not that they have more quality than Real Madrid or Bayern, but they put a lot of hard work in and have nothing to lose. Real and Bayern might've underestimated Roma, but Liverpool are warriors, a bit like us.
“I spoke to Salah and he couldn't believe we'd beaten Barcelona either! He was joking on Instagram that we'll never hear the end of Kostas Manolas saying he scored the winning goal.
“It'll be nice to see Momo again, we had a good rapport. He's a good guy, sweet and respectful, as well as being an excellent player. I am not surprised by his success at Liverpool, as he always had the quality. The only difference now is perhaps he's got more opportunities and also learned to keep a cool head in front of goal. I'm a fan of his."
