Is this a joke? They have a workhorse midfield, sure, no world class quality there but total commitment. They've got the best full backs in the league, the best centre back, a top class GK, and a world class attacking frontline where two are allowed to shine while one works his socks off for the team.
Their first XI is pretty brilliant. They could improve on a CB if Gomez continues to struggle with injuries and they could improve their attacking depth, but they look pretty set when everyone is fit. They might improve in midfield with more creative quality, but they'd need to ensure anyone coming in has the same amount of work rate.
It's a shame to say it, but they have a top class team. I'd take Robertson, Alexander-Arnold, van Dijk, Fabinho, Salah, Mane, Firmino and so would everyone else who recognises quality.
