Read this: An exception to the usual European qualification system happened in 2005, after Liverpool won the Champions League the year before, but did not finish in a Champions League qualification place in the Premier League that season. UEFA gave special dispensation for Liverpool to enter the Champions League, giving England five qualifiers. UEFA subsequently ruled that the defending champions qualify for the competition the following year regardless of their domestic league placing. However, for those leagues with four entrants in the Champions League, this meant that if the Champions League winner finished outside the top four in its domestic league, it would qualify at the expense of the fourth-placed team in the league. No association can have more than four entrants in the Champions League. This occurred in 2012, when Chelsea – who had won the Champions League the previous year, but finished sixth in the league – qualified for the Champions League in place of Tottenham Hotspur, who went into the Europa League.
