Real Madrid ease to record fourth Club World Cup title
Real Madrid have won four of the past five Club World Cups
Al Ain had shocked River Plate on penalties in the semi-final but never looked like following that up with a famous win at the Zayed Sports City Stadium in Abu Dhabi.
Midfielder Toni Kroos has won five of the past six Club World Cups – in 2013 with Bayern Munich and 2014, 2016, 2017 and 2018 with the Spanish side.
Real now hold the record for most victories in the competition, which was first held in 2000, moving one clear of Spanish rivals Barcelona.
Earlier, Copa Libertadores winners River Plate won the third-place play-off by beating Asian champions Kashima Antlers 4-0. Gonzalo Martinez scored twice on what is expected to be his final appearance before joining MLS champions Atlanta United.
