I'm interested to see how things play out with Liverpool this window. They generally don't do big business in the winter, but we know that we need someone like van Dijk, Can needs to be replaced and Coutinho is going for sure. There's also the question of whether Henderson can return to form or if he needs replacing as well. Right now we have Wijnaldum, Lallana and Ox that I would like to keep in front of the 6 and Keita coming in next season (starting Wijnaldum/Keita will be great). Wijnaldum seems like the only tactically astute midfielder we have (Lallana is up there too) and in games like the one against Sevilla they are extremely important to help calm the play, resist the press, and control the ball in midfield (it's not a huge surprise looking at that game that only Wijnaldum can feel somewhat okay about his performance of our midfielders). Coutinho isn't someone we can use in midfield in those games especially when the other team is taking the game to us, and with Moreno behind him. Pretty much everything Sevilla did came down the right side.
Anyway, tangent, I believe that next season with Wijnaldum/Keita as first choice options in front of our 6 there's an opportunity to create one of the best midfields around if we could acquire someone like Jorginho to supplement them. Fat chance of prying him out of Napoli, but I'm wondering if there are many players in a similar mould out there that could be had right now? Maybe we could revisit interest in Kondogbia?
