To be honest they can even miss top four seeing the level every team is having and how crazy this seaosn has been. I think they need a defender not because they've been bad at defense. Fabinho has been great at center back, Phillips has made a good job and Williams, while being very young, by any means he has been bad. Even Henderson when needed has been decent at the job, but the team is missing that presence in midfield. Having to play two starter midfielders at CB isn't good for the team and that has been proven. They need a CB, at least for short term, so Fabinho and Henderson can be back at midfield and hopefully for them Matip and Gomez returns soon.
