I still worry. There's work to be done still. Benteke needs to go and be replaced by a striker that fits the team better. I would like to see a player like Breel Embolo (who was just transferred), Andre Schurrle (who's up for grabs, apparently, but wants to go to Dortmund), or (fingers crossed he's as good in real life as he is in FIFA) Martin Braithwaite. It's not that we
need another striker, but we need one in case Sturridge gets injured again, so there's less of a pressure to rush him back. We don't need a repeat of the "he's back, no wait, he's back again, no....wait" like we've been having for the past two years.
We also need another centerback. Matip is a good start and I really think he'll be a success. But with Toure gone (a mistake, in my opinion), Skrtel on his way out (best of luck in Turkey, you were great for us at times), Sakho prone to injuries, Lovren continuing to not be good enough, and Joe Gomez being 12 years old, we could use another solid centerback, even if we don't have Europe this season. We should be going for an FA Cup run and shooting at the title with so few distractions.
A lot of people say we need a new leftback, but I'm not convinced that Moreno is past the point of no return. I'm not saying we don't need another fullback, but I don't think we need to replace him, unless the idea is to push him up, alleviate him of his defensive responsibility, and turn him into an all-out midfielder/winger. We need some natural wingers (I mean, people who operate naturally on the wing, not Aaron Lennon type natural wingers who can't do anything but run and cross) and moving Moreno to that position could help that out, since he's a fast, marauding wide player that has a mind for attack, and can defend from the front while still having defensive cover behind him.
I would also like to see a player come in to solidify the midfield. I think Can's temper can lead it issues and while I have a high opinion of Lucas, it seems that he may not be able to do this day-in, day-out. I think Nampalys Mendy would have been great, but Leicester snapped him up to replace the likely outgoing Kante.
