We'll need to get into the market for another centerback, its simple as that. Lovren can be a very good defender, he just needs somebody beside him to carry him. I think he can be a very good third option, but we need to find another player who can sort out the defence without Matip. Horrible showing today, Karius giving us the rest (altough i think he will become very good, just not used to it as of yet).
