There is science, there is qualified opinion, and there is just saying something in an authoritarian tone of voice.
Claiming our back three potentially looks as good as anyone in the league have, is different than saying they are, or even that they will be.
Alisson 8
Whoever 7 Van Dijk 9
has been the best functioning back three last season, though it’s important to remember they have been protected by three terriers in MF and Liverpool taking a more sensible approach than before in terms of balance. I’m still unconvinced of who their most stable CB pair is. On paper they are among the best, and they work in a good system, but I wouldn’t say the sum of the three is bigger than the parts yet.
Emerson 7
Stones 7 Laporte 8
City’s back three is well fitted to their playing style (a plus) and also orotected by Pep’s system and having ideal players for every position of the pitch. I would not be too worried if Arsenal turned up with these three at the back.
Lloris 8
Alderweireld 7? Verthongen 8
A year or two back, and this was the best back three in the league. Very good each on their own, playing in a good system, and complementing and cooperating to make the sum bigger than the parts. The system protected their relative weakness of speed and airial ability. A match made in heaven. Now I’m quite unsure how much they have declined individually, one year of contract situations seems to have eroded their safety in each others as well. Still very good, but clearly not the best.
Arsenal have big trouble in CB department, Chelsea’s are very raw.
De Gea 9
Lindelöf 7 Maguire 8
is on paper as good as Liverpool individually, if we accept De Gea’s current blip as form and not actual level. Lindelöf was probably our best player last year, yet is still the weak point in that trio. However, Lindelöf has previously been at his best when partnered with a confident, good in the air, intelligent foil (him and Granqvist looked like world beaters for Sweden in the last WC). Lindelöf’s relative weaknesses are airial duel strength. De Gea’s is command of the box Maguire complements them both in that regard. Maguire/Lindelöf’s combined weakness is speed, mitigated by an in form De Gea being the best in the world at closing down through-on-goals and shots. They are all in a good age, all are intelligent players with some leadership qualities, so I think there is a very good chance that they may develop into more than the sum of their parts. As for now, Maguire is the cog of that wheel and new to both the others, so that will obviously take time. Wether I’m right remaind to see, but I think you need to put up a more convincing argument to say it’s out of the question.
