#4 Courtois was an unnecessary purchase
While winning the Golden Glove at the World Cup and being one of the most impressive goalkeepers for the past few years in world football, Courtois' arrival seemed to have disturbed the back line a little, and the defense will take time to adjust to a new keeper and his demands of them.
His arrival seems pretty redundant as he has not made the Real Madrid goal airtight, and so far he has not done anything that Keylor Navas cannot.
Los Blancos needed a marquee signing this summer following big-name departures at the club, but they have made it in the wrong department. It was not a pressing need as Navas is a great goalkeeper capable of as much if not more than Courtois.
The jury is still out on the big Belgian. Will be interesting to see how his season develops.
