Interesting thing about recent Liverpool games where they've dropped points is that their opposition usually lets Liverpool have over 70% possession. Usually you see the counter-attacking team give up between 55-65% possession, but against Liverpool there are some extreme statistics. I think teams have had to figure out the fact that, with Liverpool playing a usually really attacking midfield 3 of Henderson, Wijnaldum and Lallana, that giving them space to play by attacking even 45% of the time is too much. Liverpool have looked even more ponderous the deeper their opposition has played, and have looked even more vulnerable on the counter-attack, giving up really easy chances. They have also looked better against the bigger teams, perversely but unsurprisingly given those bigger teams will inherently have to attack.
I think bearing all of this in mind, we should play on the counter. A back 5 of Lloris, Davies, Dier, Toby and Walker, with Dembele and Wanyama in front. Then Son and Sissoko who will be absolute musts to provide counter attacking threat, supporting Kane. Maybe drop Eriksen and play Alli, and make it about beating them on the break by being clinical. Or maybe go back to 3-4-3, with Wimmer coming in, Davies at LWB, the central beasts and then Sissoko and Son supporting Kane. Probably not on Wimmer though, as he seems really out of sorts.
Either way, I think we need to counter. Liverpool look really bad if an opposition plays really deep and takes their chances to counter. We should play the team that gives us the best chance of doing that. I'd even say if N'koudou was fit we give him a run. I don't think we win the game by playing our traditional game against them.
