Good signing! Eriksen is undoubtedly a better player for the role that we need, but given he's out for most of the season, this is as good as we could have hoped for. I'm not necessarily sure he's all that much of a better fit than Fred, but I really like Fred (in terms of the peak level he can provide). But between Fred and Sabitzer now, I'm pretty comfortable with our #8 options to go with this season. Far from the best, but very solid and we will be a very hard team to play against with that extra pressing in midfield now.
I'm sure Fred will start the next few games as Sabitzer gets eased in and adapts to the system. But good to have the depth and competition.
