Chelsea spent an unprecedented £1 billion across the last three transfer windows, but it hasn't really worked so far. The club have won two of their seven games, drawing two and losing three under new manager Mauricio Pochettino and sit 11th in the Premier League table -- already 10 points adrift of leaders Manchester City.
While they have amassed a group of some of the most-talented young players in the world, all on long-term contracts, it's possible their strategy might have been better focused towards more experienced players who could make an immediate impact.
